The 30-kg wheel is rolling under the constant moment of M = 84 N.m. The wheel has radius r = 0.48 m, has mass center at point G, and the radius of gyration is kg = 0.24 m. The coefficients of friction between the wheel and the ground is μ = 0.39 and k=0.10. If the wheel rolls without slipping, determine the angular acceleration of the wheel (in rad/s²). Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. Take g = 9.81 m/s². M Your Answer: Answer G 1
The 0.6-lb particle is guided along the circular path using the slotted arm guide. Motion occurs in the horizontal plane with negligible friction. Note that the circular part of the slot has the radius equal to 0.5 ft, and the radial position, r, is measured from the hinge and the angle is measured in the counter-clockwise direction. If the arm has an angular velocity = 4 rad/sec and an angular acceleration 6 - 8 rad/sec² at the instant when 0 = 30°, determine the force of the arm guide on the particle at the instant. Present your answer in lb using 3 significant figures. 0.5 ft 0 0.5 ft.
The 45-kg reel has a radius of gyration about its center O of ko = 220 mm. If it is released from rest, determine the total external work done to it when its center O has traveled 6.6 m down the smooth inclined plane (with angle = 35°). Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point, and proper SI unit. Take g = 9.81 m/s². 0.4 m 0.2 m²
