Structures

Question 1

How do beams act?

Answer 1

They don’t stretch, bend, or compress under loads; they are rigid

Question 2

How do joints act?

Answer 2

They connect the ends of the beams together while allowing the angles between them to change.

Question 3

How do screws act?

Answer 3

They hold joints in place, but still let the attached beams rotate.

Question 4

What happens if a joint is connected with two beams to two, different joints in a rigid structure?

Answer 4

Then the joint is part of the rigid structure.

Question 5

What does attaching any two rigid “hinges” directly together prevent?

Answer 5

It prevents either piece from spinning, making the entire structure rigid.
