Lesson details
Lesson outcome
I can explain how levers and gears transmit the rotational effects of forces.
Show transcript
A force can produce a turning effect known as a moment.
If an object is in equilibrium, there is no resultant force or moment on it.
moment = force × distance (M = Fd)
Levers can act as force or distance multipliers.
Gears can be used to transfer moments.
