Question

The dies, A and B, are tied with a rope parallel to the inclined surface as shown in the figure. The weight of the first mold A is 200 N, the coefficient of friction with the surface is 0.2, the weight of the mold B is 300 N and the coefficient of friction for it with the surface is 0.5. Find the angle of inclination of the roof preventing the two molds from moving and then find the amount of tension of the rope.
