# MEEN2003W Solid Mechanics 1

## Academic Year 2023/2024

This module offers an introduction to the fundamental ideas in solid mechanics.

Syllabus:
1. Solution of statically determinate and relatively simple statically indeterminate pin-jointed structures.
2. Buckling of slender columns.
3. Torsion of circular sections: determination of shear stress and angle of twist for statically determinate and indeterminate problems.
4. Bending of beams: shear force and bending moment diagrams, calculation of normal and shear stress distributions, beam deflections and statically indeterminate beam problems.

Laboratory Exercises (2 out of 3):
Lab 1: Strain gauging - determination of the state of stress in components subjected to axial, bending and torsional loading.
Lab 2: Investigation of the deflection of a beam in bending.
Lab 3: Investigation of the buckling behaviour of slender columns.

Note: Lab reports are to be handed in within two weeks after the date of the lab activity.

Assignments:
Two homework assignments will be set during the course of the trimester. Students will typically be given two weeks to complete each assignment.

Learning Outcomes:

On successful completion of this course the student will be able to:
1. Construct free body diagrams of engineering structures or individual components and clearly illustrate the state of loading to which they are subjected.
2. Apply the principles of static equilibrium and distinguish between problems which are easily solved (statically determinate) and those which require a more advanced solution strategy (statically indeterminate).
3. Calculate the internal stresses and the associated deflections in structural elements subjected to axial, torsional and bending loads.
4. Describe the assumptions and limitations of the analytical methods used in the course.
5. Analyse and interpret experimental data and compare the results with appropriately identified analytical solutions.

Approaches to Teaching and Learning:
Module delivery is based around weekly lectures, and two laboratory sessions. A problem-based approach is taken in lectures and tutorials, whereby the theory is taught through examples. In addition, a comprehensive set of course notes is provided which contains many worked examples, which allow students to master individual topics at their own pace. The lecturers are very approachable and are always available to meet with students to discuss any topic for which they require further clarification.
