Question

1. Assume the four-bar linkage is drawn to scale. The input link is rotating at 100rpm in the CCW direction. A constant load torque of T4=50 N−mCCW is applied to link 4. Use instant centers of velocity to answer the following. (a) Estimate the magnitude and direction of the angular velocity of the output link. Show your reasoning. (b) Estimate the mechanical advantage at the instant shown. Show your reasoning. (c) Estimate the magnitude of the torque that the driving motor must supply to the input link at the instant shown. Show your reasoning.
