IED: Institution Of Engineering Designers Exam Questions! Trivia Quiz

The shape pictured on the right is called an ellipse. An ellipse is a closed curve that is symmetric about its center. It is formed by the intersection of a cone and a plane, where the plane is at an angle to the base of the cone. The shape of an ellipse is characterized by its two axes - the major axis and the minor axis. The major axis is the longer of the two, while the minor axis is the shorter one.

Sketching is a type of drawing that is done freehand and without the use of drawing tools. It involves using simple lines and strokes to create a rough representation of an object or idea. Sketching is often used as a preliminary step in the design process to quickly explore and communicate concepts before more detailed work is done. Unlike computer-aided design or prototyping, which involve the use of specialized tools and technology, sketching relies solely on the artist's hand-eye coordination and creativity. Isometric, on the other hand, refers to a specific type of three-dimensional drawing technique.

The image shown is a pie chart. A pie chart is a circular statistical graphic that is divided into slices to represent different categories or proportions. Each slice represents a specific data point and the size of the slice corresponds to the proportion of that category in relation to the whole. Pie charts are commonly used to display data in a visually appealing and easy-to-understand format.

This answer is correct because it accurately defines innovation as an improvement made to an existing technological product, process, or system. It distinguishes innovation from the creation of something entirely new, and highlights the aspect of improvement or enhancement.

The image below is referred to as a line graph because it represents data points connected by lines, which show the trend or relationship between the variables being measured. A line graph is commonly used to display continuous data over time or other continuous intervals. In this type of graph, the x-axis represents the independent variable (such as time) and the y-axis represents the dependent variable. By plotting the data points and connecting them with lines, we can easily visualize the changes and patterns in the data.

To convert yards to feet, you multiply the number of yards by 3, since there are 3 feet in a yard. Therefore, to convert 9.25 yards to feet, you would multiply 9.25 by 3, which equals 27.75 feet.

Engineering involves the complex analysis, design, and development of solutions to technical problems. It is a discipline that applies scientific and mathematical principles to create practical solutions in fields such as mechanical, civil, electrical, and chemical engineering. Engineers use their knowledge and skills to design and build structures, machines, systems, and processes that solve real-world problems and improve the quality of life.

The average solution time is calculated by adding up the solution times of all the students and then dividing by the number of students. In this case, the solution times are 5 minutes 0 seconds, 4 minutes 32 seconds, 3 minutes 21 seconds, and 2 minutes 58 seconds. Adding these times together gives a total of 15 minutes 51 seconds. Since there are four students, we divide this total by 4 to find the average, which is 3 minutes 58 seconds.

Liquid displacement is a method commonly used by scientists and engineers to determine the volume of an irregularly shaped object. This involves placing the object in a container filled with a liquid and measuring the change in volume of the liquid. By subtracting the initial volume from the final volume, the volume of the object can be accurately calculated. This method is particularly useful for objects that cannot be easily measured using traditional tools such as a measuring cup or a tape measure.

The placement of dimensions on a working drawing is important to increase clarity and reduce confusion. By placing dimensions in a clear and organized manner, it becomes easier for the reader to understand the measurements and specifications of the drawing. This helps to avoid any misinterpretation or errors in the manufacturing or construction process. Additionally, proper placement of dimensions allows for easier referencing and ensures that all necessary measurements are included on the drawing.

An engineer would use a prototype as a full-scale physical model to demonstrate how a design functions. A prototype is a working model of a product or system that allows the engineer to test and evaluate its functionality, performance, and design. It helps identify any flaws or improvements needed before mass production or implementation. By physically testing the prototype, engineers can gain valuable insights into the design's functionality and make necessary adjustments to ensure its success.

A multi-view drawing is a drawing that shows different views of an object projected onto two or more orthographic planes. This means that the object is represented from different angles and perspectives, allowing for a comprehensive understanding of its shape and dimensions. The other options, such as cabinet pictorial, cavalier pictorial, and oblique pictorial, refer to specific types of pictorial drawings that may not necessarily show multiple views of an object.

An engine is most likely to serve as a sub-assembly in a 3D CAD model of an entire automobile. This is because an engine is a complex component that consists of various parts and subsystems, such as pistons, crankshaft, valves, and fuel system. It can be designed and assembled separately before being integrated into the overall assembly of the vehicle.

A design brief is a written plan that identifies a problem to be solved, its criteria, and its constraints. It serves as a roadmap for designers and other stakeholders involved in the design process. It outlines the goals, objectives, and requirements of a project, providing a clear understanding of what needs to be achieved. By clearly defining the problem, criteria, and constraints, the design brief helps to guide the decision-making process and ensures that the final solution meets the desired objectives.

In order to create an assembly model of the carabiner, it would be most logical to choose Part 1 as the grounded component. This is because typically, in assembly models, the grounded component is the part that remains fixed or stationary while other parts are assembled or connected to it. Therefore, Part 1 would serve as the base or foundation for the rest of the carabiner components to be attached to.

An engineering notebook is used to formally document, in chronological order, all work associated with a specific design project. It serves as a detailed record of the design process, including ideas, calculations, sketches, and any other relevant information. This allows engineers to track their progress, make revisions, and refer back to previous work if needed. A portfolio is a collection of completed projects, a design brief is a summary of project requirements, and an engineering log may refer to a record of maintenance or operational activities rather than design work.

The correct answer is "Visual" because graphs, charts, mock-ups, prototypes, and computer graphics are all visual aids that help in presenting information in a visual format. These aids enhance the understanding and retention of the content by providing visual representations of data, concepts, or designs.

Based on the drawing, the maximum diameter for hole H can be determined by measuring the distance between the two farthest points on the circumference of the hole. By doing so, it can be observed that the distance is closest to .502, making it the maximum diameter for hole H.

The range is not a measure of central tendency because it does not provide information about the typical or central value of a dataset. Instead, the range measures the spread or dispersion of the data by calculating the difference between the maximum and minimum values. Measures of central tendency, such as the mean, median, and mode, are used to describe the central or average value of a dataset.

A work plane is a 3D solid modeling feature that is used to establish a two-dimensional drawing surface in a 3D model. In this scenario, a work plane would be used to create a surface that is tangent to the outside of a sphere. This work plane can then be used as a reference to create a two-dimensional drawing or sketch on the surface of the sphere.

A design brief would be written during the Problem Identification step of the design process. This is because the design brief outlines the specific problem or challenge that needs to be addressed through the design. It includes information about the client's requirements, goals, and constraints, as well as any relevant background information. Writing the design brief at the beginning helps to clarify the scope and objectives of the design project, providing a clear direction for the subsequent steps of the design process.

To get the correct length of 67.5 cm, you should set the measurement on your manufacturing computer to 26.57 in.

A graph of vertical bars representing the frequency distribution of a set of data is called a histogram. A histogram is used to visualize the distribution of data and shows the frequency or count of data points falling within different intervals or bins. It is commonly used in statistics to understand the shape, center, and spread of a dataset. Unlike a normal distribution, which represents a specific type of distribution with a bell-shaped curve, a histogram can represent various types of distributions. A standard deviation is a measure of the spread or dispersion of data, while a Gantt chart is used for project management scheduling.

Color is a design element because it plays a crucial role in creating visual interest and impact. It can evoke certain emotions, set the mood, and create a sense of harmony or contrast within a design. Color choices can also help guide the viewer's attention and communicate specific messages or meanings. By using different colors, designers can effectively highlight certain elements, create a sense of balance or imbalance, and establish a visual rhythm within a composition.

A designer will often keep a portfolio of his or her best work to show off to prospective clients. A portfolio is a collection of a designer's past projects and designs, showcasing their skills, creativity, and expertise. It serves as a visual representation of their abilities and allows clients to assess their style and capabilities. By presenting a portfolio, designers can demonstrate their talent and impress potential clients, increasing their chances of securing new projects.

The question asks for the number of liters that a wooden barrel can hold. To convert milliliters to liters, we divide the given value by 1000. Therefore, the correct answer is 23.439 L.

A cube has six equal square faces, so to find the total surface area, we need to find the area of one face and then multiply it by six. Since each face of the cube is a square, and the length of each side is 3 inches, the area of one face is 3 inches multiplied by 3 inches, which is 9 square inches. Multiplying this by six gives us a total surface area of 54 square inches.

The correct answer is "angle." This is because an angle constraint would be used to position Block B in the desired orientation relative to Block A. The angle constraint allows for the rotation of one block around a specified axis, which would be necessary to achieve the depicted position of Block B in the After image.

Figure 4 is a two-point perspective because it has two vanishing points on the horizon line. In this perspective, the horizontal lines of the object converge towards two points on the horizon line, giving the illusion of depth and distance.

The 1 inch diameter THRU hole dimension shown on the drawing represents the size of the hole. It indicates that the hole has a diameter of 1 inch.

A full-size clay model of a new car body design would be considered a mock-up. A mock-up is a physical representation or replica of a design or product that is used to evaluate its appearance and functionality before it is produced on a larger scale. In this case, the clay model serves as a visual representation of the car body design, allowing designers and engineers to assess its aesthetics and make any necessary modifications before moving forward with production.

The given answer of 4.68 lb / cubic foot is correct. To convert the density from grams per liter to pounds per cubic foot, we need to use conversion factors. 1 pound is equal to 453.592 grams and 1 cubic foot is equal to 28.3168 liters. By multiplying the given density of 75 g/L by the conversion factor (1 lb / 453.592 g) and dividing by the conversion factor (1 ft^3 / 28.3168 L), we get the density in pounds per cubic foot as 4.68 lb / cubic foot.

Figure 3 contains an auxiliary view because it shows a 3-dimensional object from a different angle or perspective. An auxiliary view is used to provide additional information about the object that cannot be seen in the regular views. In Figure 3, the object is shown from a different direction, allowing for a better understanding of its shape, size, and features.

A cabinet pictorial is an oblique pictorial where the depth is represented as half scale but the width and height are full scale. In this type of drawing, the object is shown with one face parallel to the picture plane, and the other two faces are shown at a 45-degree angle. This technique allows for a clear representation of the object's dimensions and proportions while still providing a sense of depth.

When the pin is joined to the hinge body with an Insert constraint, it will have 1 degree of freedom. This is because the Insert constraint allows the pin to move along one axis, while restricting movement along all other axes. Therefore, the pin can only rotate around the axis of the hinge, resulting in 1 degree of freedom.

Figure 3 could result in the greatest amount of overall width variation because it has the largest number of dimensions. With a tolerance of ±0.02 inch for each dimension, the more dimensions a figure has, the greater the potential for variation in the overall width. Figures 1, 2, and 4 have fewer dimensions compared to Figure 3, so they would result in less overall width variation.

Orthographic projection is the correct answer because it is a method of representing 3-D objects on a 2-D plane using only width and height. It involves creating multiple views of the object from different angles, such as top, front, and side views, to accurately depict its shape and dimensions. This technique is commonly used in engineering, architecture, and technical drawing to communicate precise information about an object's form and structure.
