### Pre-Requisite Knowledge

Higher Grade Physics or equivalent

### Summary of Content

The aim of this module is to provide students with a foundation in the knowledge of mechanical engineering science and principles, and apply them to the design and analysis of engineering components.

### Syllabus

The teaching syllabus will cover the following areas: Solid Mechanics: Force analysis applying static equilibrium, support reactions, pin-jointed frames, method of sections, joint resolution, friction on an inclined plane, shear force and bending moment diagrams, centroids and second moment of area for symmetrical sections, parallel axis theorem for unsymmetrical sections, direct stress and strain, elastic behaviour, shear stress, bending stress, factors of safety. Dynamics: Analysis of linear and non-linear motion for translational and angular systems, Newton's laws of motion, moment of inertia, radius of gyration, angular torque and power, centrifugal force, momentum and impulse, simple harmonic motion of a singledegree-of-freedom system.

### Learning Outcomes

On completion of this module the student should be able to:1. Apply the principles of static equilibrium to 2-dimensional force systems;2. Ddetermine the shear force and bending moment variation along a loaded member;3. Evaluate stress and strain in typical engineering components under the action of direct, lateral and thermal loading;4. Apply the principles of kinematic and dynamic behaviour to particles and rigid bodies;5. Calculate energy, momentum and impulse in dynamic systems;6. Understand the principles of simple harmonic motion and vibration.

### Teaching / Learning Strategy

To support the student learning experience this module's lectures and seminars are carefully structured to present a consistent and logical progression of issues and concepts. Students are provided with formative and summative feedback via a variety of mechanisms. Feedback on coursework is provided within 3 working weeks of submission.
