Description

This module addresses the analytical aspects of both Mechanics and Thermodynamics.

Mechanics explore the analysis of the stresses induced in material under a variety of load types including direct loading, bending and torsion thought the study of complex stresses.

This mathematics part 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.
