Question 78

A uniform rod AB AB\,AB of mass 10 kg and length 6 m rests in equilibrium with A A\,A on rough horizontal ground. The rod is resting on a smooth peg at CCC, where AC=4AC = 4AC=4 m. The angle between AB AB\,AB and the ground is θ\thetaθ, where tan⁡θ=k\tan \theta = ktanθ=k

A uniform rod resting on rough horizontal ground at A and on a smooth peg at C

Given the rod is on the point of slipping.

Find, in terms of kkk, the coefficient of friction between the rod and the ground.
