An accessory belt for an engine is shown. Pulley A is attached to the engine's crankshaft and rotates clockwise. The belt tensioner consists of a frictionless idler pulley at B that is mounted to a horizontal bar D that slides in a frictionless track with a horizontal force P. Pulley C operates a hydraulic pump that requires 200 Nm. The coefficients of static friction for pulleys A and C are 0.4 and 0.6 respectively, and the radii of pulleys A and C are 110 and 80mm, respectively. Determine the minimum value of P so that belt does not slip. 130⁰ P if pulley A slips TABC, 45° D P if pulley A slips TAC P min
