Engineering Mechanics - Dynamics Chapter 17 acceleration as it rolls down the incline. Given: W 30 lb = k G 0.6 ft = μ s 0.2 = k 0.15 = r 1.25 ft = θ 12 deg = Solution: Assume no slipping Guesses F N 1lb = F = a G 1 ft s 2 = α 1 rad s 2 = F max = Given FW sin () W g a G = F N W cos 0 = F max s F N = Fr W g k G 2 = a G r = F F N F max a G Find FF N , F max , a G , , = F F N F max 1.17 29.34 5.87 lb = a G 5.44 ft s 2 = 4.35 rad s 2 = Since F 1.17 lb = < F max 5.87 lb = then our no-slip assumption is correct. *Problem 17-96
