The 76-lb force P is applied to the 180-lb crate, which is stationary before the force is applied. Determine the magnitude and direction of the friction force F exerted by the horizontal surface on the crate. The friction force is positive if to the right, negative if to the left. Assume μ = 0.43, Mk = 0.35. P Answer: F = i Ps lb
