difference between torque and tension

“Torque” is simply a measurement of the twisting force required to spin the nut up along the threads of a bolt, whereas “Tension” is the stretch or elongation of a bolt that provides the clamping force of a joint.

How do you convert tension to torque?

The Torque/Tension Equation is a method used to estimate the torque/tension relationship in an assembly. T = (K D P)/12 can be used to developt a torque value that will achieve a certain tension or clamp load. T = Torque (ft. -lbs.)

Why bolt tensioning is required?

It's accurate because tensioning provides the reliability required by delivering precise bolt loads to the joint. It's fast because in contrast to bolt torquing, bolt tensioning can eliminate cross-talk and deliver simultaneous bolt load and gasket compression across the entire joint.

What is torquing a bolt?

Torque is the amount of energy it takes to spin the nut up along the threads of a bolt. ... So, as the nut is turned (torqued) along the threads beyond this point, the steel gets pinched together between each end of the bolt assembly causing the bolt to stretch: E-L-O-N-G-A-T-I-O-N.

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.

Is tension a torque?

“Torque” is simply a measurement of the twisting force required to spin the nut up along the threads of a bolt, whereas “Tension” is the stretch or elongation of a bolt that provides the clamping force of a joint. ... Cleanliness of the bolt.

How do we calculate torque?

Calculate Torque

1. Fill your values into the equation T = K x U x D x P.
2. Solve the equation T = 1.33 times 0.20 times 0.50 inches times 13,927 lb. The total is 1,852 inches lbs.RE. Reduce the value into ft-lb. You can do this by dividing your value by 12, the number of inches in a foot.

What happens if you torque a bolt too much?

Everyone who has ever worked with fasteners has accidentally messed one up at some point. One of the most damaging ways to do that is by over-tightening, or over torquing the fastener. This can result in stripping screws, snapping screw heads and damaging pre-tapped threading.

Why do we use torque?

Torque is a crucial part of generating power from a car's engine, as it represents the load an engine can handle to generate a certain amount of power to rotate the engine on its axis. The force is measured in pounds (lb) per foot (ft) of rotation around one point. Multiply this torque force (in lb-ft.)

What is the purpose of torque wrench?

A torque wrench is a tool used to control and apply a specific torque to a fastener such as a bolt or a nut. It is a fundamental element in general mechanics, tire changing operations and industrial maintenance & repair industries, to ensure customers' safety.

At what torque will a bolt break?

If you add 33% to the torque figure listed, that should tell you the torque required to snap it. For example, if it takes 75 ft/lbs to torque to 75% yield, add 33% (25 ft/lbs) to get to the 100% yield (breakage) figure.

How do you measure the torque of a bolt that is tightening?

Calculate required bolt torque

1. normal dry: K = 0.2.
2. nonplated black finish: K = 0.3.
3. zinc-plated: K = 0.2.
4. slightly lubricated: K = 0.18.
5. cadmium-plated: K = 0.16.

Should you torque nut or bolt?

The question is often asked as to whether the nut or the bolt head should be tightened. The answer depends upon which tightening process is being used. For torque controlled tightening whether the nut is tightened and the bolt head held, or the bolt head tightened and the nut held, can be of importance.
