Moments

Question 1

What is a moment?

Answer 1

The product of force (F) x perpendicular distance (d).

Question 2

What are some real life examples of moments?

Answer 2

Opening a door.
Steering wheel.

Question 3

What is the equation for a moment?

Answer 3

M = F x d

Question 4

What are the quantities involved in M = F x d?

Answer 4

M = moments / Nm
F = force / N
d = perpendicular distance from force to pivot / m.

Question 5

What 2 conditions must exist for a body to be static?

Answer 5

1. FR = 0
2. Summation of moments about any point = 0

Question 6

What can be said about any body that is static?

Answer 6

Summation of anti-clockwise moments about any point is equal to summation of clockwise moments about the same point.

Question 7

What is the equation for a system that is static.

Answer 7

F1 x d1 = F2 x d2

Question 8

Wha this the definition for the principle of moments?

Answer 8

For a system in rotational equilibrium sum of clockwise moments = sum of anti-clockwise moments about any point.
