The formula to calculate the force from PSI is:
\[ \text{F} = \text{PSI} \cdot \text{A} \]
Where:
PSI is a unit of pressure that measures the force per unit area. To convert this into force, simply multiply it by the total area. This calculation helps determine the total force exerted on a surface given the pressure and area.
Example:
Step 1: Calculate the force:
\[ \text{F} = 50 \cdot 10 = 500 \text{ lb-f} \]
