## Press Fit Pressure Formula

The following formula is used to calculate the Press Fit Pressure.

Pfit = Fp / CA

- Where Pfit is the Press Fit Pressure (psi)
- Fp is the press fit force (lbf)
- CA is the total contact area (in^2)

To calculate the press fit pressure, divide the press fit force by the total contact area.

## How to Calculate Press Fit Pressure?

The following two example problems outline how to calculate the Press Fit Pressure.

**Example Problem #1:**

- First, determine the press fit force (lbf). In this example, the press fit force (lbf) is given as 750.
- Next, determine the total contact area (in^2). For this problem, the total contact area (in^2) is given as 3.
- Finally, calculate the Press Fit Pressure using the equation above:

Pfit = Fp / CA

Inserting the values from above and solving the equation:

Pfit =750 / 3 = 250 (psi)

**Example Problem #2: **

Using the same process as above, first define the variables required by the formula. In this case, these values are:

press fit force (lbf) = 1000

total contact area (in^2) = 5

Entering these values yields:

Pfit = 1000 / 5 = 200 (psi)
