## How do you calculate force based on torque?

The equation, Force = Torque ÷ [Length × sin (Angle)], converts torque into force. In the equation, Angle is the angle at which the force acts on the lever arm, where 90 degrees signifies direct application.

**How do you calculate screw force?**

T = F1 x D/2, where: F1 is the vector component (tangent to the ballscrew) of the force applied by the screw onto the ball bearing. Linear force is produced because of the angle of the ballscrew thread. The angle is specified by the lead, distance per revolution (distance per circumference).

### What is bolt clamp force?

Clamp Force: The compressive force on the joint members that results from the tensile force developed in a tightened bolt. This force, not torque, is what holds your bolted joint together.

**How do you calculate force from distance and torque?**

Multiply the force times the distance to find the torque. If you know the magnitude of the force (in Newtons) and the distance (in meters), you can solve for the torque, expressed in newton-meters (N∙m).

## How do you calculate bolt load?

The tensile load a fastener can withstand is determined by the formula P = St x As. To find the tensile strength of a particular bolt, you will need to refer to Mechanical Properties of Externally Threaded Fasteners chart in the Fastenal Technical Reference Guide.

**How do you calculate nut factor?**

The relationship between the torque applied to a fastener and the tension created from the resulting bolt elongation is most commonly described by T = F*K*D where T is torque, K is the nut or friction factor (nut factor for this article), D is the bolt diameter and F is the bolt tension or preload.

### How do you calculate the pull force of a bolt?

To do it, use the formula F = D x 3.1415 x L x 1600 psi — where F is bolt pull-out force — D is the bolt diameter in inches — and L is the length of the bolt embedded in grout. Calculate the pull-out strength for an anchor bolt embedded in concrete.

**How is torque calculated for nuts and bolts?**

DETERMINING TORQUE The general equation for bolt load based on applied torque is T = KFiDb where K = torque coefficient. K is a function of the coefficients of friction and collar friction in the joint, and these are based on variables such as surface finish, coatings, and so on.

## What is K in torque?

A “short form” equation for converting between torque and tension has been developed: T = K×F×D. where T is the torque measurement, K is the nut factor, F is the tension and D is the bolt diameter.

**How do you calculate pull strength?**

So force = mass multiplied by acceleration. Pull force testers are used to test the holding force of a magnet that is in contact with a flat steel plate. Pull forces are measured in pounds (or kilograms).

### How is thread torque calculated?

The basic formula T = K x D x P stated earlier takes these factors into account and provides users with a starting point for establishing an initial target tightening torque.

**How do you find force with distance and torque?**

## How do you calculate the K factor of a bolt?

K Factor (Basic)

- The formula for a 3/4 x 10, grade 8.8 bolt with dry friction surfaces would be: (30,100 lbs) x (0.750 in ÷ 12) x (0.20) = 376 ft lbs.
- The formula for a M24 x 3, class 10.9 bolt with dry friction surfaces would be: (219,500 N) x (24 mm ÷ 1000) x (0.20) = 1,054 N m.

**How do you calculate bolt tension?**

Tensile strength is the maximum tension-applied load the fastener can support prior to fracture. The tensile load a fastener can withstand is determined by the formula P = St x As.
