A
moment arm*force
5
Q
What is a first class lever?
A
Force and resistance on opposing sides of axis of rotation
6
Q
What is a second class lever?
A
Force and resistance on same sides of axis of rotation, force further away
7
Q
What is a third class lever?
A
Force closer to axis than resistance
8
Q
