ICSE Class 10 Answered
Two forces each of magnitude 2N act vertically upwards and downwards respectively at two ends of uniform rod of length 1m which is pivoted at center. Draw a diagram of arrangement and determine the resultant moment of force about the mid point of the rod.

Expert Answer
Figure shows a rod AB of length 1 m is pivoted at centre C. At A, 2N force acting upward and at B 2N force acing downward.
If we take moment of the forces about C, both moments are clockwise moments.
Moment at A = 2N × 0.5 m = 1 N m
Moment at B = 2N × 0.5 m = 1 N m
Resultant moment = 2 N m
