What is the process known as sketching?

• Drawing basic shapes to define size and shape of features

• Creating detailed 3D models

• Applying color to designs

• Assembling parts into a prototype

Answer explanation

Sketching involves drawing basic shapes to define the size and shape of features, serving as a preliminary step in design before more detailed work like 3D modeling or prototyping.

What are edge treatments in 3D modeling?

• Adding textures to surfaces

• Applying fillets and chamfers to enhance appearance

• Creating wireframe models

• Designing with virtual reality tools

Answer explanation

Edge treatments in 3D modeling refer to applying fillets and chamfers, which smooth or bevel edges to enhance the model's appearance and functionality, making it visually appealing and easier to manufacture.

What is a prototype?

• A full-sized physical model that is functional

• A digital representation of a design

• A small-scale model for display purposes

• A theoretical concept for brainstorming

Answer explanation

A prototype is typically a full-sized physical model that is functional, allowing for testing and evaluation of design concepts in real-world conditions.

What is an offset work plane?

• A plane parallel to an existing surface at a specified distance

• A plane used for cutting sections

• A plane for creating 3D animations

• A plane for applying textures

Answer explanation

An offset work plane is defined as a plane that is parallel to an existing surface but located at a specified distance from it. This allows for precise modeling and design in various applications.

What is a sub-assembly?

• A group of pre-assembled parts treated as a single unit

• A single part used in a larger assembly

• A digital model of a complete product

• A theoretical design concept

Answer explanation

A sub-assembly is defined as a group of pre-assembled parts treated as a single unit, which allows for easier assembly and organization within larger products. This distinguishes it from single parts or theoretical concepts.

What are degrees of freedom in design?

• Different ways parts can move relative to one another

• The number of parts in an assembly

• The complexity of a design

• The weight of a design

Answer explanation

Degrees of freedom refer to the different ways parts can move relative to one another in a design. This concept is crucial for understanding how components interact and function together, making it the correct choice.

What are drive constraints in modeling?

• Simulating movement of parts through specified steps

• Applying textures to surfaces

• Creating 3D animations

• Designing with virtual reality tools

Answer explanation

Drive constraints refer to simulating the movement of parts through specified steps, allowing for precise control and analysis of mechanical systems in modeling.

What is the maximum number of bike frames you can ship in one box if each frame weighs 5.67 pounds and the limit is 20 pounds?

• Three frames

• Four frames

• Two frames

• Five frames

Answer explanation

To find the maximum number of bike frames, divide the weight limit by the weight of each frame: 20 pounds ÷ 5.67 pounds/frame = 3.52. Since you can't ship a fraction of a frame, the maximum is 3 frames.

In manufacturing, tolerance refers to the (a)   in dimensions.

• Permissible variation in dimensions

• The weight of a product

• The color of a design

• The speed of production

Answer explanation

In manufacturing, tolerance specifically refers to the permissible variation in dimensions, allowing for slight deviations from specified measurements while ensuring functionality and quality.

What is minimum clearance space?

• The gap that must exist between two mating parts

• The weight of a product

• The color of a design

• The speed of production

Answer explanation

Minimum clearance space refers to the necessary gap between two mating parts to ensure proper function and avoid interference. This definition aligns with the correct answer choice.
