Structures Flashcards
1
Q
How do beams act?
A
They don’t stretch, bend, or compress under loads; they are rigid
2
Q
How do joints act?
A
They connect the ends of the beams together while allowing the angles between them to change.
3
Q
How do screws act?
A
They hold joints in place, but still let the attached beams rotate.
4
Q
What happens if a joint is connected with two beams to two, different joints in a rigid structure?
A
Then the joint is part of the rigid structure.
5
Q
What does attaching any two rigid “hinges” directly together prevent?
A
It prevents either piece from spinning, making the entire structure rigid.
