The block shown in the figure below is acted upon by its weight W=200KN, a horizontal force Q = 600kN, and a pressure P exerted by the inclined plane. The resultant R of these forces is up and parallel to the incline thereby sliding the block up it. Determine the value of P and R. Q=600KN 30° W=200KN 150 R
