# MEC2402 Stress Analysis

 Semester 1, 2022 Springfield On-campus Units : 1 Faculty or Section : Faculty of Health, Engineering and Sciences School or Department : School of Engineering Student contribution band : Band 2 Grading basis : Graded Version produced : 27 June 2022

## Staffing

Examiner: David Buttsworth

## Requisites

Pre-requisite: CIV1501 or Students must be enrolled in one of the following Programs: GCEN or METC or MEPR or GCNS or GDNS or MENS or GEPR

## Overview

Every structure or machine has to perform its intended function within a predetermined and acceptable probability of failure. Stress analysis addresses the strength and rigidity of structures and machines while under load. It predicts how force is carried through a structure or machine and how the materials at any point in any individual member resist the force. As such, stress analysis is essential to the design function and the analysis function. Every engineer who has to make a judgement on the strength and stability of any structure, machine or mechanism, no matter how simple or how complex, must understand the fundamental principles of stress analysis.

## Course learning outcomes

The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:

1. review and apply the principles of static equilibrium to the analysis of structures such as pressure vessels, beams, and torsion members;
2. evaluate stress and strain within various structures by applying the appropriate engineering theories;
3. formulate solutions to problems requiring the application of suitable engineering theories for stress and strain;
4. locate and calculate the highest equivalent stress on any section of a beam or shaft undergoing simple or combined loading, and determine if yield failure will occur.
