Moments & Turning Forces Flashcards
1
Q
The fixed point where a force turns around is called a ……….
A
pivot
2
Q
The turning effect is called a ……….
A
moment
3
Q
What is the equation to find the size of a moment? Give units
A
Moment (Nm) = Force (N) x perpendicular distance (m)
4
Q
True or False? Moments have a direction
A
Yes, moments can move clockwise or anticlockwise
5
Q
How do you find the perpendicular distance?
A
Measure along a line that is at a right angle to the direction of the force
6
Q
What is the principle of moments?
A
If an object is in equilibrium the sum of clockwise moments will be equal to the sum of anti-clockwise moments
