1
Q
What are moments caused by?
A
Moments are caused by a force exerted on a certain distance from a pivot point
2
Q
Equation for moments
A
Moment = Force X Perpendicular distance from the pivot point
M = F x d
3

Nm
4
Q
What is the principle of moments?
A
in rotational equilibrium
sum of clockwise moments = the sum of the anti-clockwise moments.
5
Q
When do you use the equation F1 x d1 = F2 x d2
A
When you need to figure out one of their force values or distances via re-arranging
