4. The uniform slender rod has a mass m= 20 kg and length L = 0.5 m. As the frame accelerates forward the rod is held in the position shown at a steady angle 0 = tan (3/4) by the stop at A. Determine the magnitude of the reaction force at stop A if the acceleration is a = 6 m/s. A = a L. A

The 250-kg wheel has a radius of gyration about its center O of ko = 260 mm, and radius r = 0.4 m. When the wheel is subjected to the constant couple moment M = 64 N.m, it starts rolling from rest. Determine the total angular impulse L (in N.m.s) about the wheel's IC after 7.3 seconds if the wheel has been rolling without slipping. Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point. Take g = 9.81 m/s². M Your Answer: Answer

The 20-kg wheel has a radius of gyration about its center O of ko = 300mm as shown in Fig.5. When the wheel is subjected to the couple moment, it slips as it rolls. Determine the angular acceleration of the wheel and the acceleration of the wheel's mass center O. The coefficient of kinetic friction between the wheel and the plane is ur = 0.5. 0.4 m M = 100 N-m

4 The uniform 16.1-lb slender bar is hinged about a horizontal axis through O and released from rest in the horizontal position. Determine the distance b from the mass center to O which will result in an ini- tial angular acceleration of 16.1 rad/sec?, and find the force R on the bar at O just after release. G 12" 12"
