Question

Two blocks each of mass M are connected to the ends of a light frame as shown in below figure. The frame is rotated about the vertical line of symmetry. The rod breaks if the tension in it exceeds T0. Find the maximum frequency with which the frame may be rotated without breaking the rod.

Solution

The correct option is A


Consider one of the blocks. If the frequency of revolution is f, the angular velocity is ω = 2 πf.The

acceleraton towards the centre is v2l = ω2l = 4π2f2l. The only horizontal force on the block is the

tension of the rod. At the point of breaking, this force is T0.So from Newton's second law,

T0 = M.4π2f2l

or f = 12 π[T0Ml]12
