Calculate Shock Force









Formula

To calculate the Shock Force (SF):

\[ SF = L \times \left( 1 + \sqrt{1 + \frac{2 \times FD \times A \times E}{L \times LG}} \right) \]

What is a Shock Force?

A shock force is a force seen by a rope attached to a falling object. It is crucial in understanding the impact forces in scenarios such as climbing, rescue operations, and other applications where ropes are used to arrest falls.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ SF = 200 \times \left( 1 + \sqrt{1 + \frac{2 \times 10 \times 0.5 \times 30000}{200 \times 100}} \right) \approx 200 \times (1 + \sqrt{1 + 15}) \approx 200 \times (1 + 4) = 1000 \text{ lbf} \]

The Shock Force is approximately 1000 lbf.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ SF = 150 \times \left( 1 + \sqrt{1 + \frac{2 \times 5 \times 0.3 \times 25000}{150 \times 80}} \right) \approx 150 \times (1 + \sqrt{1 + 12.5}) \approx 150 \times (1 + 3.54) = 680.85 \text{ lbf} \]

The Shock Force is approximately 680.85 lbf.
