Moments and Centre of Mass Flashcards
1
Q
Moment
A
The product of the force applied to a distance perpendicular to the direction of the force
2
Q
Moment =
A
force x distance
3
Q
Equilibrium of a moment
A
When an object is in equilibrium, the sum of the clockwise moments about any point is equal to the sum of the anti=clockwise moments about the same point
4
Q
Centre of gravity
A
The point at which we can take its entire weight to act
5
Q
Centre of mass
A
The point at which we can take its entire mass to be concentrated
6
Q

A
- There is no net force acting in any direction
2. There is no net turning force about any point
