Discuss the below in detail:
Q: A 15-kg double pulley has a radius of gyration of 125 mm and is attached to a 10-kg slider block by a pin at point G. The system is at rest when constant forces PA and PB are applied to the cords as shown. Knowing that after 2 s the velocity of point A is 3.3 m/s to the left and the velocity of point B is 5.7 m/s to the right determine the magnitudes of the forces PA andPB.
