Question
A wheel of diameter 3 m is shown in fig. 2 with axle at 0. A force F = 8 N is applied at Q in the direction shown in figure. Calculate the moment of force about:
(i) centre o, and
(ii) point p.

Solution
(i) Moment of force = applied force x perpendicular distance from the line of action
Moment of force at O = 8 x 1.5 = 12 Nm
(ii) Momemnt of force = applied force x perpendicular distance from the line of line
Moment of force at P = 8 x 3 = 24 Nm
