## Stresses in a Shaft

A shaft PQ is twisted when subjected to equal and opposite torques on either side. Consider a section perpendicular to the shaft's axis through an …

## Deformation in a Circular Shaft

A unique property of circular shafts is that under torsion, every cross-section remains plane and undistorted, rotating as a solid rigid slab. To …

## Circular Shaft – Stresses in Linear Range

Consider a case when the torque applied to the circular shaft is within Hooke's law limit, so there is no permanent deformation. Now, recall the …

## Angle of Twist – Elastic Range

Consider a circular shaft of length L and a uniform cross-section of radius r subjected to a torque at its free end. The maximum shearing strain in the …

## Angle of Twist: Problem Solving

The electric motor exerts a 700 N-m torque on an aluminium shaft, causing it to rotate at a constant speed. Pulleys B and C experience torques of 300 N-m …

## Design of Transmission Shafts

The design specifications required for a transmission shaft are the power transmitted by the shaft and its rotation speed. Based on these specifications, …

## Stress Concentrations in Circular Shafts

Recall the elastic torsion formula, applicable to a circular shaft with a uniform cross-section. Here, it is assumed that the shafts are loaded at their …

## Plastic Deformation in Circular Shafts

When materials are subjected to stresses exceeding their yield strength, plastic deformation occurs, causing a permanent strain. In the case of circular …

## Circular Shafts – Elastoplastic Materials

Within the elastic limit, the maximum stress in a solid circular shaft varies linearly with a radial distance from its axis. As the torque increases, the …

## Residual Stresses in Circular Shafts

In elastoplastic materials, residual stress can develop when the material undergoes plastic deformation due to high shearing stress or large strains. When …

## Torsion of Noncircular Members

During torsional loading, the cross-sections of the circular shafts remain plane and undistorted since they are axis-symmetric. However, due to the lack …

## Thin-Walled Hollow Shafts

Consider a small portion of width 'dx' from a thin-walled hollow shaft of thickness 't' subjected to torsional loading. Since the portion …

## Optimized Sealing Process and Real-Time Monitoring of Glass-to-Metal Seal Structures

Residual stress is an essential factor to keeping the hermeticity and robustness of a glass-to-metal seal structure. The purpose of this report is to …

## Micromechanical Tension Testing of Additively Manufactured 17-4 PH Stainless Steel Specimens

This study presents a methodology for the rapid fabrication and micro-tensile testing of additively manufactured (AM) 17-4PH stainless steels by combining …
