Without the careful measurement of hydrostatic forces, structures like the Hoover Dam or the Tamar Bridge could not have been built. The analysis of fluid flow in pipes is of key importance in many areas from water distribution networks to cooling systems and heat exchangers, whilst the calculation of stresses and strains in rods under torsion is important in analysing engine transmissions and jet engine power shafts. These areas of solid and fluid mechanics underpin much of civil engineering and mechanical engineering design, and are some of the key areas you will explore on this module.
Solid Mechanics is the study of solid objects under loads and their resulting behaviour (stress and deformation); Hydrostatics the study of pressure in stationary fluids, and hydrodynamics the flow of fluids such as water and air. In this module, you will encounter fluid and solid static equations and principles, including tension, compression, hydrostatic forces, pressure and head, continuity, momentum and energy, and stress and strain in rods and beams under various loadings. You will learn how to calculate forces from statics fluids, flow in pipes, stresses on beams, etc. In a hands-on laboratory session, you will measure the force from a water jet, impacting on different surfaces, and then present your work in the form of a group report.
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; and with concepts of energy and head used to solve pipe flow problems, and 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. You will also be familiar with the concepts of stress and strain in solid mechanics and able to calculate these properties for rods which are stretched and twisted, and beams loaded in different configurations. You will also learn about the deformation of solid objects under these loads, and be able to answer the question “will it break?”
Prerequisite module: ECM1102 or equivalent
The aim of this module is to introduce you to fundamental concepts of solid mechanics and fluid mechanics, separated into two sections (half a term each). For solid mechanics this includes stress/ strain relationships, axial members, rods and beams, and failure. For fluid mechanics this covers fluid properties, continuity and energy equations, momentum, and engineering concepts such as buoyancy and hydrostatics.

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.
