Description

Mechanics studies the consequences of appying loads in terms for deflection, and material failure. It also explores how strain guage results can be use to calculate stresses.

This mathematics section of this module consists of topics from Intergal and Differential Calculus, Linear Algebra and Complex Numbers. These topics include differental equations and applications, Laplace Transforms, De Moivre's Theorem, Fourier Transforms, Gaussian Elemination and z Transforms.

 

Learning Outcomes

On completion of this module the learner will/should be able to;

1.

Calculate beam deflection for standard load cases

2.

Determine stresses in components due to applicaiton of strain gauges

3.

Determine factor of safety against failure under complex load using failure theories

4.

Solve dynamic systems involving inertia, linear and angular displacement, velocity and acceleration.

5.

Calculate powers of complex numbers using theorems of DeMoivre and Euler

6.

Solve linear systems using Gaussian Elemination and apply this to engineering problems

7.

Evaluate eigenvalues and eigenvectors
