## Description

Introduction to solid and structural mechanics: analysis of statically determinate structures; stress and strain; behaviour of beams and columns; analysis of deformations; torsion.

This course introduces emerging civil and natural resources engineers to the concepts of solid mechanics. The aim is to provide the fundamentals for the analysis of problems involving statically determinate bodies and loadings. The course develops the concepts and analysis of engineering stress and strain, pressure vessels, torsion, simple constitutive and failure theories, and bending.

## Learning Outcomes

At the conclusion of this course you should be able to:

1.  Calculate and plot internal forces and moments: axial forces, shear forces, bending moments, and torques;  (Washington Accord WA1) (UC EIE3)

2.  Define and compute engineering stresses and strains in solid bodies for different loadings and combinations of loadings (Washington Accord WA1) (UC EIE3)

3.  Qualitatively describe the deformation of solid bodies under various loadings (Washington Accord WA1 (UC EIE3).

4.  Use Mohr's circle to determine stress and strain transformations, principal components and maximum shear components (Washington Accord WA1) (UC EIE3)

5.  Explain and apply simple constitutive and failure theories (Washington Accord WA1) (UC EIE3)

6.  Apply the integration and moment area methods to calculate deflections of statically determinant beams  (Washington Accord WA1) (UC EIE3)

7. Explain the assumptions and limitations inherent in analytical techniques for solid body mechanics (Washington Accord WA1) (UC EIE3).

8.  Analyse and interpret experimental data and use experimental data to explore and communicate how the assumptions and techniques of solid mechanics apply in the context of non-idealised conditions (Washington Accord WA1, WA2, WA4, WA10) (UC EIE2, EIE3, EIE4).

## Assessment

Assessment Due Date Percentage  Description
final exam 45% Learning Objectives assessed 1-7
Lab assignment 15% LO Ass 1-5, 7, 8
Online Quizzes (9x11) 10% LO Ass 1-7
Mid term test 30% LO Ass 1-4, 7

The assessment for this course will comprise three main components – a test, a final exam, and assignments.

Quizzes are held on LEARN each week, and will cover material up to that point in the course with a focus on the specific material in lectures for that week. Quizzes cannot be made up if missed for any reason and special consideration is not applicable as they are worth < 10% individually.

The final quiz grade will comprise the top 9/11 individual quiz marks to allow students to miss up to two quizzes without any effect on their course grade. Quizzes will come available each Monday and will be due as posted on LEARN. Quizzes are designed to assess mastery of key concepts and should not take more than 1 hour to complete.

Homework problems are posted for each week on LEARN. These problems are not assessed, they are for your own practice and self-study. Numerical answers will be made available, and worked solutions will be posted at the end of the weekly quiz period.

Academic Remedies for Special Consideration on Major Assessment Items:

Mid Term Test:

Students will be offered an equivalent alternative test in order to demonstrate their true unimpaired level of mastery of the learning objectives. The alternative test will be held in Week 7. The mark on this alternative test will replace the original test mark in the course grade calculation unless a student declines or does not respond to the offer of the alternative exam, in which case the original mark will be used. Students will not be advised of their original mark as part of this process.

Lab Assignment:

An extension will be granted for evidence-supported requests. Extensions will typically be for up to one week, but the duration will be considered on a case-by-case basis. Students seeking an extension must contact the course coordinator as soon as possible with evidence of their situation. Requests that come after the due date will only be considered in exceptional circumstances.

Final Exam:

Students will be offered an equivalent alternative exam in order to demonstrate their true unimpaired level of mastery of the learning objectives. The alternative exam will be held in the week following the exam period. The mark on the alternative exam will replace the original exam mark in the course grade calculation unless a student declines or does not respond to the offer of the alternative exam, in which case the original mark will be used. Students will not be advised of their original mark as part of this process.

## Textbooks / Resources

Beer, Johnston, Dewolf and Mazurek; Mechanics of Materials ; 7th; McGraw Hill, 2014.

#### Where to submit and collect work

Lab assignments must be submitted to the applicable assignment drop box on LEARN by 5.00 pm, three weeks after the allocated laboratory section. Late submissions will incur a 20% penalty per day late. Further instructions for the lab assignment are available on LEARN and on the provided lab assignment sheet.
