What is the difference between an Exploded and an Assembled drawing?

• Exploded drawings show the relationship between the parts and the order of the assembly, whereas the Assembled drawings show the parts put together. 

• Exploded drawings show the overall shape of the drawing, whereas the Assembled shows the flattened view. 

Why is the single point of attachment a fault in this design?

• It isn't tight enough

• It serves as a point of rotation (similar to an axle)

• It uses the wrong material

What is the purpose of bracing?

• To provide a catching mechanism for game objects. 

• To provide an aerodynamic design for improved speed. 

• To reinforce a structure by providing a second support at a different angle.

What is Center of Gravity?

• The point where the structure’s weight pushes with average strength

• The point where the “average” weight of a structure is going to push down

• The calculated strength of a structure where weight is the lightest

Which of the following correctly shows the support base for this fan?

• 
• 
• 
• 

A structure will tip over when:

• The center of gravity is not directly over the support base

• The center of gravity remains directly over within the base

Which of the following tools is best suited to precisely measure the inner dimension of a piece of C-Channel?

• Measuring Tape

• Caliper

• Square

• Compass
