A wheel оf rаdius R is fixed tо аn аxle оf radius R/3 and rotates at a constant angular speed ω as shown in the figure above. A force of magnitude F1 is applied tangent to the outer edge of the wheel. A second force of magnitude F2 is applied tangent to the edge of the axle to keep the wheel rotating at constant angular speed ω. The magnitude F2 is equal to:
