Engineering Mechanics - Dynamics Chapter 16 *Problem 16-72 Part of an automatic transmission consists of a fixed ring gear R , three equal planet gears P , the sun gear S , and the planet carrier C , which is shaded. If the sun gear is rotating with angular velocity ω s determine the angular velocity c of the planet carrier . Note that C is pin-connected to the center of each of the planet gears. Given: s 6 rad s = r s 4in = r p 2in = Solution: s r s p 2 r p = p s r s 2 r p = p 6.00 rad s = p r p c r s r p + () = c p r p r s r p + = c 2.00 rad s = Problem 16-73 When the crank on the Chinese windlass is turning, the rope

Unformatted text preview: on shaft A unwinds while that on shaft B winds up. Determine the speed of block D if the crank is turning with an angular velocity . What is the angular velocity of the pulley at C ? The rope segments on each side of the pulley are both parallel and vertical, and the rope does not slip on the pulley. Given: 4 rad s = r A 75 mm = r C 50 mm = r B 25 mm = Solution: v P r A = v P' r B = 442...
