Repeat Problem with β = 90°.

Figure shows a four-bar mechanism. Link 2 rotates counterclockwise at a constant 10 rad/s. The weight of links 2 and 3 is negligible, and link 4 is 17 kg. The radius of gyration of link 4 relative to the center of gravity is 45 mm. For β = 45°, determine the following:

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

2. The angular acceleration of link 4,

3. The inertial force and torque of link 4,

4. The pin forces at B and C, and

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