**About Screw Torque to Linear Force Calculator (Formula)**

In mechanical engineering, understanding the relationship between torque and linear force is crucial for the design and analysis of various systems. The Screw Torque to Linear Force Calculator is a valuable tool that allows engineers and technicians to convert the torque applied to a screw into the linear force exerted by that screw. This conversion is essential in applications where precision and accuracy are paramount, such as in the design of fasteners, clamps, and other mechanical components. By using this calculator, you can ensure that your mechanical systems operate efficiently and safely.

### Formula

The formula for calculating linear force is: LF = ST / (L * Sin(a)), where LF is the linear force, ST is the screw torque, L is the length of the screw, and a is the angle of inclination.

### How to Use

Using the Screw Torque to Linear Force Calculator is simple. First, measure the screw torque applied in your application. Next, determine the length of the screw and the angle of inclination at which the torque is being applied. Input these values into the formula, and the calculator will provide you with the corresponding linear force. This straightforward process enables engineers to make quick and accurate calculations for their designs and analyses.

### Example

Let’s consider an example where:

- Screw Torque (ST) = 100 Nm
- Length of the screw (L) = 0.5 m
- Angle of inclination (a) = 30 degrees

To calculate the linear force:

- Convert the angle from degrees to radians if necessary, but for this example, we can use the sine value directly.
- Calculate Sin(30 degrees) = 0.5.
- Plug the values into the formula:
- LF = 100 / (0.5 * 0.5) = 100 / 0.25 = 400 N.

This result indicates that the linear force exerted by the screw is 400 Newtons, providing important information for design and load-bearing considerations.
