Engineering Mechanics - Dynamics Chapter 16 Problem 16-97 Due to slipping, points A and B on the rim of the disk have the velocities v A and v B . Determine the velocities of the center point C and point E at this instant. Given: v A 5 ft s = θ 45 deg = r 0.8 ft = v B 10 ft s = φ 30 deg = Solution: Guesses a 1f t = b t = Given a v A b v B = ab + 2 r = a b Find , () = a b 0.53 1.07 ft = ω v A a = 9.38 rad s = v C ra = v C 2.50 ft s = v E 2 r 2 + = v E 7.91 ft s = Problem 16-98 The mechanism used in a marine engine consists of a single crank
