The homogenous semicylinder has a mass of 20 kg and mass center at G. If force P is applied at the edge, and r = 300 mm, determine the angle 0 at which the semicylinder is on the verge of slipping The coefficient of static friction between the plane and the cylinder is µs = 0.3. Also, what is the corresponding force P for this case?
