What is a moment? |
The turning effect of a force is called it's moment. |
|
|
|
What is the equation used to measure the size of the moment? |
M = f × d M = moment of the force, newton - metres (Nm) f = force, newtons (N) d = perpendicular distance from the line of action of the force to the pivot, metres (m) |
|
|
|
You can increase the moment by... |
-increasing the force -increasing the distance to the pivot |
M = f × d |
|
|
It is easier to undo a wheel-nut by: -Using a long spanner -Using a short spanner And why? |
-the long spanner because it increases the distance between the line of action of the force and the pivot. |
