The given equation in the image is:

\[
80 \times 10^6 \, \text{N/m}^2 = \frac{P}{0.002 \, \text{m}^2} + \frac{0.02P \, (\text{N.mm}) \times 0.02 \, \text{m}}{2.66 \times 10^{-7} \, (\text{m}^4)}
\]

We need to solve for \( P \).

### Step 1: Convert units for consistency
- In the second term, the units for force are given in N.mm (Newtons multiplied by millimeters). To maintain unit consistency, we should convert millimeters to meters:
  \[
  0.02 \, \text{N.mm} = 0.02 \times 10^{-3} \, \text{N.m}
  \]
  This gives:
  \[
  0.02P \times 0.02 = 0.00002P \, \text{Nm}
  \]

Thus, the second term becomes:
\[
\frac{0.00002P}{2.66 \times 10^{-7} \, \text{m}^4}
\]

### Step 2: Rearranging the equation
The equation is now:
\[
80 \times 10^6 = \frac{P}{0.002} + \frac{0.00002P}{2.66 \times 10^{-7}}
\]

Let me solve this step by step.The solution for \( P \) is approximately:

\[
P = 139,085 \, \text{N} \, (\text{Newtons})
\]

1. How do unit conversions affect the consistency of equations in physics?
2. What is the significance of the cross-sectional area in pressure calculations?
3. How does converting between different force units (N.mm vs. N.m) change the problem?
4. How can simplifying terms in an equation help with solving it?
5. What is the role of moment of inertia (denoted by \( m^4 \)) in structural analysis?

**Tip**: Always check unit consistency before solving physics problems to avoid calculation errors!

Solve for P in the equation: 80 × 10^6 N/m² = P / 0.002 m² + (0.02P × 0.02 m) / (2.66 × 10^(-7) m⁴)

This problem involves solving for force P in an equation that combines stress and moment of inertia concepts. It requires understanding unit conversions, algebraic manipulation, and applying structural mechanics principles. Suitable for engineering students.
