A
The object will turn
2
Q
What is a couple
A
A pair of forces which act PARALLEL but in OPPOSITE directions
3
Q

A
Resultant linear
Turning force
4
Q
What is the turning force called
A
Usually called a torque rather than a moment
5
Q
How so you work out the torque of a couple (nm)
A
Size of one of the forces(n) * perpendicular distance between the forces (m)
6
Q
How to work out the muscle seesaw force
A
Momentum anticlockwise distance pivot = momentum a clockwise distance pivot
7
Q
Moment of a force(nm) equals what
A
Force (n) * perpendicular distance from pivot (m)
