Question

When a nut is tightened on the bolt the nature of stress in the bolt is

Answer 1

your answer

when nut is tightened on the bolt the nature of stress on the bolt is tensile stress that arises because of the torque produced when we turn the bolt to tighten it therefore it is in form of tensile strength

Answer 2

Answer:

The answer is the nature of stress in the bolt is Tensile stress.

Explanation:

Torque on bolt positions the bolt in Tension. The pressures are tensile stresses. There can likewise be torsional tension in the bolt, which is detrimental. That is underestimated by lubricating the lines first, with anti-seize, thread locker (before cure), or surface treatment of the threads. In some circumstances, it is common practice to support off nuts slightly behind torquing to facilitate torsional stress.

The numerous practical and generally assumed equations for representing the tightening procedure exists shown below.

$T_{\mathrm{I}}=F\left[\frac{P}{2 \pi}+\frac{\mu_{\mathrm{T}} R_{\mathrm{T}}}{\cos \alpha}+\mu_{\mathrm{B}} R_{\mathrm{B}}\right]$

Hence,

Tensile stress exists as an amount associated with extension or tensile forces. Usually, tensile stress is described as the force per unit area and represented by the symbol σ.
