Engineering Mechanics - Dynamics Chapter 16 *Problem 16-28 Morse Industrial manufactures the speed reducer shown. If a motor drives the gear shaft S with an angular acceleration α = ke b t , determine the angular velocity of shaft E at time t after starting from rest. The radius of each gear is listed. Note that gears B and C are fixed connected to the same shaft. Given: r A 20 mm = r B 80 mm = r C 30 mm = r D 120 mm = k 0.4 rad s 2 = b 1s 1 = t 2s = Solution: ω 0 t t ke bt d = 2.56 rad s = E r A r B r C r D = E 0.160

Unformatted text preview: rad s = Problem 16-29 Morse Industrial manufactures the speed reducer shown. If a motor drives the gear shaft S with an angular acceleration = k-3 , determine the angular velocity of shaft E at time t 1 after gear S starts from an angular velocity when t = 0. The radius of each gear is listed. Note that gears B and C are fixed connected to the same shaft. Given: r A 20 mm = r B 80 mm = 414...
