2
Q
What is the moment of a force about a pivot
A
M=Fd, where d is the perpendicular distance from the line of action of the force F to the pivot
M= Moment (newton metres, Nm) F= Force (newtons, N) d= distance from the pivot (metres, m)

Q
To increase to moment of a force……
A
Increase F or increase d
M=Fd
4
Q
What can Levers be used for?
A
Levers can be used to exert a force that is greater than the effort
