Your question: Which of the following stresses are associated with the tightening of a knot on a bolt?

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.

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 do you tighten bolts with?

Wrenches are used to tighten and loosen fasteners, mainly nuts and bolts. Wrenches are generally made from a chrome-plated steel alloy. The material makes wrenches both durable and simple to clean.

What should be tightened the nut or the bolt head?

There is no simple answer to this as in some instances, it is perfectly acceptable to tighten the bolt head while holding the nut in place. In other situations, it’s acceptable to tighten the nut.

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.

Which type of the stress is induced in a screw thread?

Which type of stress is induced in a screw body? Ans- Torsional shear stress as it is induced because of the torque or twisting moment.

What kind of stresses does the welded joint undergo?

Direct and torsional shear stress.

How do you tighten torque?

To use a torque wrench, adjust the handle and set it to a specific level of torque. Use the tightener on the end of the handle to lock it in place. Then, fit it over the socket, nut, or bolt and turn it clockwise to tighten it.

What does it mean to torque 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.

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.

Why do you tighten the nut and not the bolt?

In such situations, it will, in general, be important as to whether the bolt head or nut is tightened. The reason is that each face will have a different friction coefficient. … If it had a lower friction value then the preload would be increased if the bolt head was tightened.

Why do you torque a bolt?

Torque is used to create tension. Bolts are used to affix two components so that they can resist tensile (pulling apart) and shearing (sliding apart) forces. After the nut has been turned onto the bolt, additional torque causes the nut to turn and stretch the bolt.

What are the stresses induced in threaded fasteners when transverse loading?

Tensile stresses (due to stretching of the bolt) and torsional shear stress (due to frictional resistance at the threads) are the stresses induced in threaded fasteners when transverse loading.

What is the purpose of bolt tightening?

Tightening the bolt puts the shank in tension, counteracted by compressive forces on the contact surfaces of the head and the nut, transferred from the parts.

How does a bolt tighten?

What happens as a bolt is tightened? When using a traditional wrench to tighten a bolt, the torque applied to the nut causes it to slide up the inclined plane of the threads. This relative motion between the nut and the bolt attempts to reduce the distance between the bearing surfaces of the bolt and nut.
