Question 50
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. The coefficient of friction between the rod and the ground is 0.75.
Given the rod is on the point of slipping.
Find tanθ\tan \thetatanθ.
