(30%) A slender rod of length - 1.3m and mass m-30 kg has its ends at P and Q pinned to sliders that constrained to follow guides as shown in figure 5. A force F 100 N is applied at the end Q. when the rod is released from rest at 6-40 deg. The mass of the sliders at P and Q are negligible. Consider the plane of the motion to be vertical and all surfaces smooth, and determine: (a) The angular acceleration of the rod when it is released. (b) The reactions on the rod at ends P and Q when the rod is released. E
