Question 24

A uniform rod AB AB\,AB of mass 16 kg and length 8 m rests in equilibrium with A A\,A on rough horizontal ground. The rod is resting on a smooth peg at CCC, where AC=5AC = 5AC=5 m. The angle between AB AB\,AB and the ground is θ\thetaθ, where tan⁡θ=0.8\tan \theta = 0.8tanθ=0.8

rod AB inclined above horizontal ground with a smooth peg at C

Given the rod is on the point of slipping.

Find the coefficient of friction between the rod and the ground.
