20N.3.SL.TZ0.6b

A bar rotates horizontally about its centre, reaching a maximum angular velocity in six complete rotations from rest. The bar has a constant angular acceleration of $0.110 rad s^{- 2}$ . The moment of inertia of the bar about the axis of rotation is $0.0216 kg m^{2}$ .

(b)

Draw the variation with time $t$ of the angular displacement $θ$ of the bar during the acceleration.
