A crate, which has a weight of W, is placed on an inclination. The force P is applied to prevent the crate from sliding down the inclination. a) Determine the minimum required force P, if the coefficient of static friction is u31. b) Determine the friction force (in magnitude) acting at the bottom of the crate if the force P=P1 and the coefficient of statie friction is µs1. c) Determine the minimum required force P, if the coefficient of static friction is u32. Use W=450 N, a=35°, us1=0.4, Hs2=0.75 and P=115 N. The minimum required force P in N is (if the coefficient of static friction is µs1) (round to the nearest integer): N The magnitude of friction in N is (if the force P-P, and the coefficient of static friction is u1) (round to the nearest integer): N The minimum required force P in N is (if the coefficient of static friction is µs2) (round to the nearest integer): N
