A 150-lb block is placed on a 29∘ incline and released from rest. The coefficient of static friction between the block and the incline μs is 0.31. (a) Determine the maximum and minimum values of the initial tension T in the spring for which the block will not slip when released. (b) Calculate the friction force F (positive if up the slope, negative if down) on the block if T = 77 lb. Assume W = 150 lb, θ = 29∘. Answers: (a) Tmax = lb, Tmin = Ib (b) F = Ib

A worker develops a tension T in the cable as he attempts to move the 50−kg cart up the 21∘ incline. Determine the resulting acceleration a of the cart if (a) T = 129 N and (b) T = 206 N. Neglect all friction, except that at the worker's feet. The acceleration a is positive if up the slope, negative if down the slope. Answers: (a) T = 129 N, a = m/s2 (b) T = 206 N, a = m/s2

Problem 1. You are trying to slide a heavy block-like object, of mass m, along a flat floor, with a coefficient of kinetic friction μk between the object and the floor. You wrap a rope around the object, and pull with a force of magnitude F. Your goal is to slide the block along the floor at some constant speed. You do not necessarily have to pull horizontally; you can pull at any angle α to the horizontal. (20 points total) (a) Find an expression for F as a function of α, μk, g, and m. ( 8 points) (b) What would be the optimum choice of α, so that the block can be pulled with the smallest value of F ? (8 points) (c) If μ = 0.6, what is the optimum value of F computed in part b ? (4 points)
