Question

Figure P14.23 shows a slider-crank mechanism. Link 2 rotates clockwise at a constant 200 rad/s. The weight of link 2 is negligible, link 3 is 3 lb, and link 4 is 2 lb. The radius of gyration of link 3 relative to the center of gravity is 3 in. For , determine the following:

1. The linear acceleration of link 4 and the center of gravity of link 3,

2. The angular acceleration of link 3,

3. The inertial force and torque of the coupler link,

4. The pin forces at B and C, and

5. The torque to drive the mechanism in this position.
