The Problem

A shaft whose material is not known operates in a mission critical machine. To

evaluate the operational mechanical reliability of the shaft, its material must be

identified. Thus, scientific determination of the shaft's key material properties is

requested. Fig. $1$ shows a picture of the shaft.

The Tasks

You are required to carry out an engineering analysis on the shaft. This will require

you to select and apply appropriate computational and analytical techniques to model

the complex response of the shaft to increasing torsional loads whilst recognising the

limitations of this technique.

In addition, you will need to deploy engineering practice which requires you to use

practical laboratory and workshop skills to carry out torsional loading and microscopic

examination of the microstructure of the shaft.

You are advised that selection and application of appropriate equipment in the IC$0\mathrm{.}38$

and IC$0\mathrm{.}42$ laboratories, as well as implementation of suitable engineering

technologies and processes will support you to obtain the parameters needed to

complete the engineering analysis task. It will also enable you to acquire some useful

information on the composition of the microstructure of the material. It is expected

that you recognise the limitations of these tasks too.

Based on the findings of the two designed experiments and application of your

previous knowledge on mechanics of solid materials as well as material properties in

general, you are required to draw conclusions and advise on what the material of the

shaft is$.$
