# MEC2402 Stress Analysis

 Semester 1, 2019 Online Short Description: Stress Analysis Units : 1 Faculty or Section : Faculty of Health, Engineering and Sciences School or Department : School of Mechanical and Electrical Engineering Student contribution band : Band 2 ASCED code : 030701 - Mechanical Engineering Grading basis : Graded

## 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

## Synopsis

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.

## Objectives

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.

## Topics

## Important assessment information

1. Attendance requirements:
It is the students' responsibility to attend and participate appropriately in all activities (such as lectures, tutorials, laboratories and practical work) scheduled for them, and to study all material provided to them or required to be accessed by them to maximise their chance of meeting the objectives of the course and to be informed of course-related activities and administration.

2. Requirements for students to complete each assessment item satisfactorily:
To satisfactorily complete an assessment item a student must achieve at least 50% of the marks or a grade of at least C-. Students do not have to satisfactorily complete each assessment item to be awarded a passing grade in this course. Refer to Statement 4 below for the requirements to receive a passing grade in this course.

3. Penalties for late submission of required work:
Students should refer to the Assessment Procedure http://policy.usq.edu.au/documents.php?id=14749PL (point 4.2.4)

4. Requirements for student to be awarded a passing grade in the course:
To be assured of receiving a passing grade a student must obtain at least 50% of the total weighted marks available for the course (i.e. the Primary Hurdle), and have satisfied the Secondary Hurdle (Supervised), i.e. the end of semester examination by achieving at least 40% of the weighted marks available for that assessment item.

Supplementary assessment may be offered where a student has undertaken all of the required summative assessment items and has passed the Primary Hurdle but failed to satisfy the Secondary Hurdle (Supervised), or has satisfied the Secondary Hurdle (Supervised) but failed to achieve a passing Final Grade by 5% or less of the total weighted Marks.

To be awarded a passing grade for a supplementary assessment item (if applicable), a student must achieve at least 50% of the available marks for the supplementary assessment item as per the Assessment Procedure http://policy.usq.edu.au/documents/14749PL (point 4.4.2).

5. Method used to combine assessment results to attain final grade:
The final grades for students will be assigned on the basis of the weighted aggregate of the marks (or grades) obtained for each of the summative assessment items in the course.

6. Examination information:
In a Restricted Examination, candidates are allowed access to specific materials during the examination. The only materials that candidates may use in the restricted examination for this course are: writing materials (non-electronic and free from material which could give the student an unfair advantage in the examination); hand-held, battery-operated calculator which cannot hold textual information (students must indicate on their examination paper the make and model of any calculator(s) they use during the examination); an A4 sheet (two sides) containing any information that they believe will be relevant for the examination. The A4 sheet must be submitted with the exam booklets. No other materials are permitted in the examination. Charts, tables and graphs needed for the solution of the examination problems will be provided with the examination paper.

7. Examination period when Deferred/Supplementary examinations will be held:
Any Deferred or Supplementary examinations for this course will be held during the next examination period.

8. University Student Policies:
Students should read the USQ policies: Definitions, Assessment and Student Academic Misconduct to avoid actions which might contravene University policies and practices. These policies can be found at http://policy.usq.edu.au.

## Assessment notes

1. Students must familiarise themselves with the USQ Assessment Procedures (http://policy.usq.edu.au/documents.php?id=14749PL).

2. Referencing in Assignments must comply with the Harvard (AGPS) referencing system. This system should be used by students to format details of the information sources they have cited in their work. The Harvard (APGS) style to be used is defined by the USQ library’s referencing guide. These policies can be found at http://www.usq.edu.au/library/referencing
