Numerical

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

Concept: Moment (Turning Effect) of a Force Or Torque
