A Moment is the Turning Effect of a Force Flashcards
1
Q
What is the formula relating Force, moment and perpendicular distance between line of action and pivot
A
Moment = Force x perpendicular distance between line of action and pivot
2
Q
What do the force on the spanner do?
A
Causes a turning effect or moment on the nut
3
Q
What would a larger force mean?
A
A larger moment
4
Q
How does using a longer spanner help?
A
The same force can exert a larger moment because the distance from the pivot is greater
5
Q
What do you need to do to get the maximum moment?
A
You need to push at right angles (perpendicular) to the spanner
6
Q
What does pushing at any other able mean?
A
A smaller moment because the perpendicular distance between the line of action and the pivot is smaller
