Moments Flashcards
1
Q
The Moment of a Force is?
A
The turning effect of a force
2
Q
Load is?
A
The weight of an object
3
Q
The Equation for Moments is?
A
M=F x d
Nm=N x m
Moments= Force x Distance
4
Q
Distance in terms of Moments is?
A
The perpendicular distance from the line of action to the pivot
5
Q
Moments can be increased by?
A
- Increasing the size of the force
- Increasing the length of the distance
6
Q
The sum of clockwise moments=?
A
= Sum of anticlockwise moments
7
Q
How do levers make it easier to do work?
A
They increase distance from the pivot, so less force can be applied to get the same moment (M=Fd)
8
Q
How do gears affect moments?
A
- their teeth interlock, transmitting the rotational effect of a force from one place to another
- a larger gear will cause a bigger moment (distance from the pivot is greater) + will turn slower
