Moments

Moment of a force = force x distance from pivot to force

1. a) A(0.4) = 2N (.3m)

A(0.4) = .6nm

A= .6nm/0.4m = 1.5N

b) A (0.20) = 0.25(4N)

= 1/0.20

A= 5

2. a) A (0.25) = 0.15(4N) + 0.40(1N)

= C(0.25) = 0.6N + 0.4N

= 1N/0.25

A= 4

b) D (0.3) = 0.40(5N) + 0.20(1N)

= D(0.3) = 2+0.2 = 2.2N/0.3

A= 7.3

3. A (0.25) = 0.20(5N)

A(0.25)/0.25 = 1/0.25

A= 4
