PROBLEM 5: The upper block is attached to the ground as shown in the figure by a short rope. The coefficient of friction between the blocks is 0.25 while the angle of friction between the lower block and the horizontal ground is 30°. (a) Determine the tension in the rope, in N, when the lower block is about to move. (b) Determine friction force, in N, under the 900 N block when it is about to move. (c) Determine the horizontal force P, in N, required to initiate motion.
