Find the value of p in the relation `tau = (YL^(p))/(cos theta)`
where Y is the young's modulus, `tau` is torque and L is the length.

Explanation

To find the value of \( p \) in the relation \( \tau = \frac{Y L^p}{\cos \theta} \), we will analyze the dimensions of each term involved in the equation.

### Step 1: Write down the dimensions of each term.
- **Torque (\( \tau \))**: Torque is defined as the product of force and the distance from the pivot point, which can be expressed as:
\[ \tau = R \times F \]
where \( R \) is the distance (length) and \( F \) is the force. The dimension of force is given by:
