The 25-kg wheel is rolling under the constant moment of M = 73 N-m. The wheel has radius r= 0.52 m, has mass center at point G, and the radius of gyration is kG = %3D 0.21 m. The coefficients of friction between the wheel and the ground is ls = 0.26 and lk = 0.18. 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 G Your Answer: Answer

The wheel is attached to the spring. The mass of the wheel is m=20 kg. The radius of the wheel is 0.6m. The radius of gyration ke=0.4 m. The spring's unstretched length is Lo=1.0 m. The stiffness coefficient of the spring is k=2.0 N/m. The wheel is released from rest at the state 1 when the angle between the spring and the vertical direction is 8-30°. The wheel rolls without slipping and passes the position at the state 2 when the angle is 8=0°. The spring's length at the state 2 is L2=4 m.
