Engineering Mechanics - Dynamics Chapter 21 Problem 21-50 The rod assembly is supported by journal bearings at A and B , which develops only x and z force reactions on the shaft. If the shaft AB is subjected to a couple moment M 0 j and at the instant shown the shaft has an angular velocity ω j , determine the reactions at the bearings when the assembly is in the position shown. Also, what is the shaft's angular acceleration? The mass density of each rod is ρ. Given: ω 5 rad s = c 500 mm = ρ 1.5 kg m = d 400 mm = a 500 mm = e 300 mm = b 300 mm = g 9.81 m s 2 = M 0 8Nm = Solution: I xx ab + c + () + c + 2 3 da 2 + e e 2 12 + ea b + 2 e 2 2 + +
