I.E.D. Warm-up Review Fall 2015

Engineers are responsible for designing most products used in today's society. They use their technical knowledge and skills to create and develop various products that meet the needs and demands of society. From electronics to automobiles, engineers play a crucial role in designing and innovating products that improve our daily lives. Their expertise in areas such as mechanical, electrical, and software engineering allows them to design products that are safe, efficient, and functional.

The design process is an engineering method that follows a logical sequence of steps to address a specific problem or need and ultimately generate a solution. It involves identifying the problem, gathering relevant data, brainstorming ideas, evaluating and selecting the best solution, creating prototypes or models, testing and refining the design, and finally implementing the solution. This systematic approach ensures that engineers consider all necessary factors and constraints to develop an effective and efficient solution.

Label A is pointing to the vanishing point. In perspective drawing, the vanishing point is the point on the horizon line where parallel lines appear to converge. It is used to create the illusion of depth and distance in a two-dimensional drawing.

A line that touches an arc or circle at only one point and is perpendicular to the arc's radius is called a tangent.

If the sweep feature is applied to the shape and path pictured, it would most likely result in Figure 4. This is because the sweep feature creates a new shape by moving the original shape along the path. In this case, Figure 4 is the only option where the shape has been moved along the path in a way that creates a different figure.

Based on the given information, the maximum number of bike frames that can be shipped in one box is 3. This can be calculated by dividing the weight limit of 20 pounds by the weight of each bike frame, which is 5.67 pounds. Since the weight of 3 bike frames is 17.01 pounds, it is within the weight limit. Therefore, 3 bike frames can be shipped in one box at one time.

OSHA, or the Occupational Safety and Health Administration, is the correct answer. OSHA is a government organization that is responsible for assuring the safety and health of workers in the United States. They achieve this mission by setting and enforcing standards that employers must follow to ensure a safe and healthy work environment. OSHA plays a crucial role in protecting workers from hazards, promoting workplace safety, and reducing the risk of accidents and injuries on the job.

The stages a product goes through from concept and use to eventual withdrawal from the market place is referred to as the product life-cycle. This term encompasses the entire lifespan of a product, including its development, introduction, growth, maturity, and decline. Understanding the product life-cycle is crucial for businesses as it helps them make strategic decisions regarding marketing, pricing, and product improvements at each stage.

The correct answer is construction line. Construction lines are used in technical drawings to help in the construction of objects. They are lightly drawn lines that are used as guides and are not part of the final drawing. In this case, line type C is labeled as a construction line.

A Cabinet Oblique sketch is a 3-dimensional sketch that is drawn true size in its height and width but foreshortened in its depth. In this type of sketch, the depth lines are drawn at a 45-degree angle to the horizontal lines, creating a more realistic representation of the object. This technique is commonly used in technical drawings and architectural designs to accurately depict objects in a visually appealing way. Isometric sketch, Cavalier Oblique sketch, and Two-point Perspective sketch are not drawn true size in their height and width, making them incorrect choices for this question.

When a single mate constraint is applied between two opposing surfaces in an assembly, it restricts the movement in one direction, leaving three degrees of freedom remaining between the two parts. These remaining degrees of freedom allow for movement in two perpendicular directions and rotation around one axis.

In an orthographic sketch, construction lines are used to project the size of an object from one view to another. These lines are typically light and drawn in a dashed or dotted style. They help in accurately representing the dimensions and proportions of the object in different views, aiding in the overall understanding of the object's shape and structure.

Gathering demographic data helps in discovering information about the family income. Demographic data provides insights into the economic status of a population, including their income levels. This information is valuable for various purposes, such as market research, targeting specific customer segments, determining purchasing power, and understanding the socio-economic background of a particular group. By collecting demographic data, organizations can make informed decisions and tailor their products or services to meet the needs and preferences of different income groups.
