PROBLEM : The 550 KN block shown is contact with a 45° incline. The coefficient of static friction is 0.25. Compute the value of the horizontal force P necessary to: 1. Just start the block up the incline. 2. Just prevent motion down the incline. 3. If P = 400, what is the amount and direction of the friction force.
