Figure 2 shows a slider-crank mechanism that is being driven by a constant clock

Question

Figure 2 shows a slider-crank mechanism that is being driven by a constant clock-wise couple M = 5 lb in. All the components are homogeneous, with the weights and dimensions as indicated. When the mechanism is in the position shown, the angular velocity of the crank is omega 1 = 12 rad/s clockwise. Neglect friction and assume that motion is in a vertical plane. draw the complete kinematic diagram of the mechanism in initial position, draw the complete kinematic diagram of the mechanism in final position (crank has rotated 90 degrees), Using a datum for the gravitational potential energy through point O. determine the initial and final potential energies. Determine the kinetic energy in position 1. Formulate the equation for the kinetic energy in position 2. Determine the angular velocity of crank in position 2.

Explanation / Answer

yes, that's a wheel...
