## ECM1202 - Basic Mechanics (2019)

DESCRIPTION - summary of the module content

Without the careful measurement of static and hydrostatic forces, structures like the Hoover Dam or the Tamar bridge could not have been built. This examination of the static behaviour of solids and fluids, which underpins much of civil engineering and mechanical engineering design, is just one of the key areas you will explore on this module.

In this module, you will encounter fluid and solid static equations and principles, including tension compression, learn how to calculate forces from stagnant fluids, stresses on beams, etc. In a hands-on laboratory session, you will measure the force from a water jet, heating different surfaces, and then illustrate your results in diagrams.

On completing this module, you will be familiar with the basics of fluid and solid principles by which practically all static and hydrostatic problems are solved; you will have an excellent foundation in critical measurement techniques and be proficient in using a hydraulic bench, in this case, equipped with a pump and simple system to measure flow rate.

Prerequisite module: ECM1200 Core Engineering or equivalent

AIMS - intentions of the module

The aim of this module is to introduce you to fundamental concepts of solid mechanics and fluid mechanics, separated into two sections. For solid mechanics this includes stress/strain relationships, axial members, rods and beams. For fluid mechanics this covers fluid properties, continuity and energy equations, momentum, and engineering concepts like buoyancy and hydrostatics.

RE-ASSESSMENT NOTES

If a module is normally assessed entirely by coursework, all referred/deferred assessments will normally be by assignment.

If a module is normally assessed by examination or examination plus coursework, referred and deferred assessment will normally be by examination. For referrals, only the examination will count, a mark of 40% being awarded if the examination is passed. For deferrals, candidates will be awarded the higher of the deferred examination mark or the deferred examination mark combined with the original coursework mark.
