What is the displacement of point P when a wheel turns half time forward? R = 4m

To determine the displacement of point \( P \) when the wheel turns half a revolution forward, we first need to understand a few key concepts.

### Step 1: Understand the Problem
- **Radius \( R \)**: The radius of the wheel is given as \( 4 \) meters.
- **Half Revolution**: When a wheel turns half a revolution, the point \( P \) originally on the circumference of the wheel will move from one point on the circle to a point directly opposite on the circumference.

### Step 2: Calculate the Displacement
Displacement is the straight-line distance between the initial and final positions of point \( P \).

- The initial position of \( P \) is at some point on the circumference.
- After a half revolution, \( P \) moves to the point directly opposite its starting position.

### Geometry of the Problem
- The distance between two opposite points on a circle is the diameter of the circle.
- The diameter \( D \) is twice the radius \( R \).

So, the displacement \( d \) of point
