Question

Two opposite and parallel forces each of magnitude 3 Newton act as a couple at the two ends of uniform rod of length 1 m freely pivoted at its centre. Calculate total moment of the couple​

Answer 1

Answer:

Magnitude of force applied on each end = 10 N

The moment of force τ = r × F. Hence in bothe the cases, moment of force is in the clockwise direction, and the moment of forces add to one another

The magnitude of τ = 2 × 10 × 2 = 40 Nm in the clockwise directi

Answer 2

Answer:

Two bodies have masses in the ratio 3: 4. When a force is applied on the body, it moves with an acceleration of 3 ms. How much acceleration will the same force produce in the other body?
