Clutches, Brakes, Couplings, and Flywheels

The clutch is described as a machine element used to connect or disconnect two shafts together to transmit torque or power. The clutch works on the principles of friction. The clutch is commonly used in automobiles to transfer power from the driving shaft to the driven shaft.

Question

The 30-kg wheel is rolling under the constant moment of M = 99 N-m. The wheel has radius r= 0.45 m, has mass center at point G, and
the radius of gyration is kg = 0.23 m. The coefficients of friction between the wheel and the ground is ls = 0.40 and Hk; = 0.12. If the
wheel rolls without slipping, determine the necessary static frictional force between the wheel and the ground. Please pay attention:
the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. Take g
