I.E.D. Final Exam Part 2 (Spring 2013)

A regularly recurring sequence of events or actions is referred to as rhythm. Rhythm implies a pattern or flow that repeats in a predictable manner. It can be observed in various aspects of life, such as music, dance, poetry, and even natural phenomena like the rising and setting of the sun. The concept of rhythm brings a sense of order, harmony, and continuity to these sequences, making them more organized and pleasing to the senses.

Balance is a condition in which different elements are equal or in the correct proportion. In art and design, balance refers to the distribution of visual weight in a composition. It can be achieved through symmetrical or asymmetrical arrangements of elements, creating a sense of stability and harmony. When elements are balanced, the viewer's eye is guided smoothly across the artwork, resulting in a pleasing and cohesive overall aesthetic.

The sketch type shown to the right is a two-point perspective sketch. This can be determined by the presence of two vanishing points, which are used to create the illusion of depth and three-dimensionality in the drawing. In a two-point perspective sketch, the lines converge towards two points on the horizon line, giving the impression of depth and distance. This type of sketch is commonly used in architectural and interior design drawings to accurately represent objects and spaces in a realistic manner.

The hand-written messages on the fire truck sketch are examples of annotations. Annotations are notes or comments added to a drawing or sketch to provide additional information or clarification. In this case, the messages are likely providing details about specific features or components of the fire truck design. Annotations are commonly used in engineering and design to communicate important details and instructions to others who may be involved in the manufacturing or construction process.

The insert constraint would be the best constraint to use when placing a pin inside a hole. This constraint ensures that the pin is inserted fully into the hole, preventing any gaps or misalignment. It ensures a secure and tight fit between the pin and the hole, providing stability and preventing any movement or dislodging of the pin.

Emphasis refers to the special importance, value, or prominence given to something. It is a way of highlighting or drawing attention to a particular aspect or idea. In communication or design, emphasis is used to make certain elements stand out and create a focal point. It helps in conveying the intended message effectively and guiding the audience's attention towards the key information or concept.

Chain dimensioning, also known as point-to-point dimensioning, establishes dimensions from one point to the next. This means that each dimension is measured and specified in relation to the previous dimension, creating a chain of measurements. This method is commonly used when dimensions need to be precise and accurately aligned, such as in mechanical engineering or architecture. It allows for clear and consistent communication of measurements, ensuring that each point is accurately positioned in relation to the others.

Radial symmetry refers to an arrangement where an object can be divided into multiple identical parts around a central axis. This means that if the object is rotated around its central axis, it will still maintain its overall shape. This concept is often observed in nature, such as in flowers or starfish, where the parts of the organism radiate out from a central point. Therefore, the correct answer is radial symmetry.

Circles should have a center mark and are dimensioned with a leader line to identify the diameter. The center mark is used to locate the exact center of the circle, while the diameter is a straight line passing through the center and touching two points on the circumference.

The correct answer is virtual teaming. This term refers to project teams that collaborate and communicate remotely, using technology such as email, Skype, and file sharing. It highlights the fact that team members are not physically present in the same location but work together virtually to achieve project goals. "Wireless working" and "digital teaming" do not accurately capture the concept of remote collaboration, and "cyber-clan" is not a commonly used term in this context.

A detailed view is used to show a magnified view of features that are too small to adequately specify in another view. It provides a close-up view of specific areas or components, allowing for a more detailed examination and understanding of the design. This view is commonly used in technical drawings to provide additional information and clarity to the viewer.

Circles and arcs that share the same center point are concentric. This means that their centers coincide, but their radii are different, resulting in circles or arcs that are nested within each other. The term "concentric" is used to describe this relationship between circles and arcs with the same center point.

The correct answer is Occupational Safety and Hazard Association (OSHA). OSHA's mission is indeed to assure the safety and health of America's workers by setting and enforcing standards. OSHA is a government organization that focuses on workplace safety and ensures that employers provide a safe and healthy working environment for their employees. They establish regulations and guidelines to prevent workplace hazards, conduct inspections, and enforce compliance with safety standards. OSHA plays a crucial role in protecting workers and reducing workplace accidents and injuries.

A section view is used to show the "inside" or hidden features of an object. It is created by slicing the object in half and removing one portion to reveal the internal details. This type of view is commonly used in technical drawings and engineering designs to provide a clear understanding of the object's internal structure and components.

A decision matrix is a tool used to compare design solutions by evaluating them against specific criteria, typically based on project requirements. It allows for a systematic and objective comparison of different options, helping to identify the most suitable solution. By assigning weights to different criteria and scoring each option accordingly, a decision matrix provides a structured approach to decision-making, enabling stakeholders to make informed choices.

Arcs should have a center mark and are dimensioned with a leader line to identify the radius. The center mark is used to indicate the center point of the arc, while the radius is the distance from the center to any point on the arc. This allows for accurate measurement and identification of the arc's size and position.

In a design brief, various elements are included to guide the design process. These elements typically consist of the problem and design statement, client and target consumer information, and constraints. However, the one item that is not typically found in a design brief is the solution. The design brief outlines the problem to be solved and provides information about the client and target consumer, but it does not provide the actual solution to the problem. The solution is developed through the design process based on the information provided in the design brief.

The term "value" refers to the lightness or darkness of a color in relation to a scale ranging from white to black. It is a measure of the intensity or brightness of a color. When a color is closer to white, it is considered to have a higher value and is lighter. Conversely, when a color is closer to black, it is considered to have a lower value and is darker. Value is an important element in art and design as it helps create contrast, depth, and dimension in a composition.

When two parts are assembled, the amount of overlap they have with each other is called interference. This refers to the intentional overlapping or interference between parts to ensure a tight fit and proper functioning of the assembly. The other options, such as allowance, tolerance, and limit dimensions, refer to different concepts related to dimensions and specifications, but they do not specifically describe the amount of overlap between assembled parts.

The American National Standards Institute (ANSI) is a private, non-profit organization that coordinates the development and use of voluntary consensus standards in the United States. ANSI's role is to ensure that standards are developed through a transparent and consensus-based process, involving stakeholders from various industries. These standards help to promote safety, efficiency, and interoperability in products and services, and they are widely recognized and adopted both nationally and internationally. OSHA, IOS, and ASME are not involved in the coordination of voluntary consensus standards in the United States.

Figure 3 represents the most complete and appropriately dimensioned multi-view drawing because it includes all necessary views (front, top, and side) of the object. It also provides clear and accurate dimensions for each view, allowing for a comprehensive understanding of the object's shape and size.

An auxiliary view is a view that is used to show features located on an angled or inclined surface in their true dimensions. It is typically created by projecting the features onto a plane that is perpendicular to the angled surface. This allows for a more accurate representation of the features and helps in understanding their shape and size. Therefore, an auxiliary view is the correct term for this type of view.

The section lines in regions A and C in the front view of the drawing indicate that the cutting plane contacts material only in those regions. This means that the cutting plane intersects and cuts through the material in regions A and C, but does not come into contact with any material in region B. The section lines are used to represent this intersection and indicate the areas where the cutting plane is in contact with the material.

The term "allowance" refers to the tightest possible fit between two mating parts. It represents the intentional gap or space between the parts, allowing for proper assembly and movement. Tolerance, on the other hand, refers to the acceptable variation in dimensions of a part. Limit dimension represents the maximum or minimum allowable size for a part. Interference refers to the unwanted contact or overlap between mating parts.

Limit dimensioning refers to the maximum and minimum limits within which a feature can be made, based on the tolerance of the dimension. It helps to ensure that the manufactured part falls within the acceptable range of variation. By specifying limit dimensions, engineers can control the variability in the manufacturing process and ensure that the final product meets the required specifications.
