1.3 Moments Flashcards
1
Q
Moment Equation
A
M=FxD (perpendicular distance)
2
Q
Principle of moments
A
For a system which is in a state of rotational equilibrium, the summation of the clockwise moments about a point is equal to summation of the anti clockwise moments about the same point
3
Q
Couples definition
A
Two forces that act in opposite directions, not along the same line, and which cause rotation. A couple produces an unbalanced moment.
4
Q
Centre of gravity definition
A
The point where the entire weight of an object seems to act
5
Q
Centre of mass definition
A
The point where the entire mass of an object seems to act
6
Q
Moment definition
A
The product of the force x the perpendicular distance to a pivot point
