Question

The wheel and axle have forces applies tangentially as shown in the figure. There is also a frictional torque of 0.02 Nxm on the wheel, once the wheel starts moving. The radius of the axel is 20 cm and the radius of the wheel
is 60 cm and F1 = 2.4 N, F2 = 3.0 N and F3 = 1.2 N.

a. Calculate the net torque on the moving wheel due to the applied forces F1 F2 and F3.

b. What direction of rotation would the applied forces cause? Explain.

c. What is the direction of frictional torque? Explain.

d. Calculate the net torque on the wheel and axle.

The image displays a mechanical diagram of a wheel subjected to multiple forces acting at different points. 

In the diagram:

- A circular wheel is illustrated with two concentric circles. The larger circle has a radius labeled as 66 cm, and the smaller inner circle (likely representing an axle or hub) has a radius labeled as 29 cm.

- Three forces are applied to the wheel:

  1. **F₁ = 2.4 N**: This force is applied tangentially at the top of the larger circle pointing to the right. 

  2. **F₂ = 3.0 N**: This force is exerted tangentially at the bottom right of the larger circle, also pointing to the right.

  3. **F₃ = 1.2 N**: This force acts at the inner circle, likely towards the center along the radius from the center toward the bottom left, though the exact orientation isn't specified.

This setup suggests an analysis of rotational dynamics or equilibrium involving torque and force vectors. The differences in radius and force magnitudes would influence the resulting motion or balances of these forces.
