Question
A wheel that is initially at rest has forces applied to it, as shown in (Figure 1), and it begins to rotationally accelerate.
Calculate the net torque about the axle of the wheel shown in (Figure 1). Assume that a friction torque of 0.45 m⋅N opposes the motion.

This diagram illustrates the application of forces on a circular object with specified radii and force vectors.
#### Diagram Details:
- **Circular Object Specification:**
- The object consists of two regions with different radii.
- **Inner Circle Radius:** 12 cm
- **Outer Circle Radius:** 24 cm
- **Force Vectors:**
- Three forces are applied at different points along the circumference of the object.
- **35 N Force:** Directed at a 135° angle from a reference line (often taken as horizontal to the right).
- **28 N Force:** Directed vertically upward.
- **18 N Force:** Directed horizontally to the left.
- **Force Application Points:**
- The forces do not intersect at the center of the circle, suggesting tangential or off-center applications, which may introduce torque or rotational effects.
This setup can be used to study the equilibrium, torque, and resultant force vector calculations in physics, providing a practical example of forces acting at angles and their impact on rotational motion.
