The formula to calculate the Force (F) from Horsepower (HP) is:
\[ F = \frac{HP \times T \times 550}{D} \]
Where:
A horsepower is a unit of power that is length times force divided by time. Therefore, the force can be calculated from horsepower if both time and distance/length are known.
Let's say the horsepower (HP) is 10 ft-lbf/s, the time (T) is 5 seconds, and the distance (D) is 2 feet. Using the formula:
\[ F = \frac{10 \times 5 \times 550}{2} = 13750 \, \text{lbf} \]
So, the force (F) is 13750 lbf.
