### Magnetic Forces on a Current-Carrying Rectangular Wire Loop

A current-carrying rectangular wire loop with a width \( a = 0.115 \) m and length \( b = 0.215 \) m lies in the xy-plane, supported by a nonconducting, frictionless axle of negligible weight. A current of \( I = 2.25 \) A travels counterclockwise in the circuit (see the figure below). Calculate the magnitude and direction of the force exerted on the left, right, top, and bottom segments of the wire (in N) by a uniform magnetic field of \( 0.500 \) T that points in the positive x-direction. Find the magnitude of the net torque (in \( \text{N} \cdot \text{m} \)) on the loop about the axle.

#### Diagram Explanation
![Wire Loop Diagram](wire-loop-diagram.png)

The diagram shows a rectangular loop of wire positioned horizontally in the xy-plane. It consists of left, right, top, and bottom segments. The loop is subjected to a magnetic field represented by the vector \( \mathbf{B} \), which points in the positive x-direction. The current flows counterclockwise, i.e., up through the left segment, right through the top segment, down through the right segment, and left through the bottom segment.

Axes are labeled as follows:
- \( x \)-axis: Horizontal direction to the right.
- \( y \)-axis: Vertical direction upwards.
- \( z \)-axis: Perpendicular to the xy-plane coming out of the page.

### Task Breakdown
Use the given variables to complete the following calculations:

1. **Left Segment of the Wire**:
    - Magnitude of Force (N)
    - Direction of Force

2. **Right Segment of the Wire**:
    - Magnitude of Force (N)
    - Direction of Force

3. **Top Segment of the Wire**:
    - Magnitude of Force (N)
    - Direction of Force

4. **Bottom Segment of the Wire**:
    - Magnitude of Force (N)
    - Direction of Force

5. **Net Torque**:
    - Find the magnitude of the net torque on the loop about the axle.

### HINT
- Use the formula for the magnetic force on a current-carrying wire segment in a uniform magnetic field: \( \mathbf{F} = I
