Problem 4 The acceleration of a connecting rod is defined by the relation =6. with angles in radians. The rod is released from rest when =20. a) Determine the maximum angular velocity. b) Determine the angular velocity when t=2s. c) If the rod has a mass of 10kg and mass moment of inertia of 0.3kgm2, what moment must be applied to reach the angular acceleration when =20 ? Draw an FBD, use Equations of Motion. Assume gravity is vertical downward
