Which of the following stresses are associated with the tightening of a nut on a stud?

Explanation: Bending stress comes when there is some kind of eccentric load. When nut is tightened, the bolt will pull itself and stretching will be there resulting in the tensile stress. Torsional stress will come when the nut is rotating.

When nut is tightened over bolt the stresses generated are?

Torsion is the twisting of the bolt when applying the tightening torque. When a bolt is tightened it is subjected to tensile stress as preload is introduced but also to torsion stress as a result of thread friction.

What stresses act on screw fastening?

Screw fasteners can fail in several modes but the dominant stress in a screw under tension is tensile. Other potential failure modes of screws are stripping shear failure at the thread roots, and fatigue failure.

What are the stresses acting on a nut and a bolt?

When a nut is tightened over a screw following stresses are induced: (a) Tensile stresses due to stretching of the bolt (b) Torsional shear stress due to frictional resistance at the threads.

What are the different types of the stresses induced in bolts?

The experimental results show that the fully grouted bolt suffers tensile, compressive, bending and shear stress at the same time.

What are the stresses acting on a nut and bolt?

Why is torque Tightening important?

those nuts that keep your wheel fastened to the studs on your axle and the bolts that secure and keep your engine assembled were installed at the proper torque to keep them from coming loose. When accurate torque is not applied to the bolts and nuts, they wear out quickly and can cause failure.

What is the tightening torque?

Torque tightening is the accurate application of torque to a nut so that a bolt can hold its load securely without breaking. When you apply the right amount of torque, the bolt is properly stretched so that it can act as a solid spring to clamp the two materials together.

What is the effect of the initial tightening load on the bolt?

If the nut does not loosen, this bolt tension remains as the clamping force. This clamping force is called the bolt pre-load or pre-tension, initial static load. When tightening the bolt head is held stationary and nut is twisted so that the bolt shank will not feel the thread friction torque.
