In the figure shown, block R has a mass of 90 kg and block Q has a mass of 45 kg. They are connected by a rope parallel to the inclined plane. The coefficient of static friction between R and the plane is 0.10, and between Q and the plane is 0.40. Calculate the value of the angle at which motion impends down the plane. Calculate the magnitude of the tension in the rope.
