Question:

For the instant represented collar B is moving along the fixed shaft in the X-direction with a constant velocity v_B = 4 m/s. Also at this instant X = 0.3 m and Y = 0.2 m. Calculate the velocity of collar A, which moves along the fixed shaft parallel to the Y-axis. Solve, first, by differentiating the relation X² + Y² + Z² = L² with respect to time and, second, by using the first of Eqs. 7/4 with translating axes attached to B. Each clevis is free to rotate about the axis of the rod.
