A uniform 20-kg tube rests on a loading dock with its end B located at a distance

Question:

A uniform 20-kg tube rests on a loading dock with its end B located at a distance a = 0.25 m from the edge C of the dock. A cable attached at end A forming an angle θ = 60° with the tube will be used to move the tube. Knowing that the coefficient of static friction between the tube and the dock is 0.30, determine 


(a) The smallest value of P for which motion of the tube impends, 


(b) Whether the tube tends to slide or to rotate about the edge C of the dock.image
