moments of force Flashcards
1
Q
The moment of a force is
A
the turning effect of the force
2
Q
Direction (sense) of a Moment
A
clockwise or anti clockwise
3
Q
How to calculate moment of a force
A
Moment = (size of force) x (perpendicular distance of line of action of force from turning point)
Moment = F x d perpendicular
4
Q
perpendicular
A
at an angle of 90° to a given line, plane, or surface or to the ground
5
Q
Equilibrium
A
balanced
Zero acceleration
zero resultant force
Zero resultant moment taken about any point
6
Q
the principle of moments
A
The sum of the clockwise moments is the sum of the anticlockwise moments
