ABSTRACT
Engineers need to select and use materials to produce a whole range of mechanical systems, machines and artefacts, and also need to know how these materials will stand up to the loads imposed on them when in use. You will be introduced to and use the principles laid down by Hooke and Young when you study the eff ects of loading static engineering systems in the fi rst outcome of this unit. In the second outcome of this unit, Newton ’ s laws of motion will underpin your study of dynamic systems. In the third outcome of the unit you will apply Archimedes ’ and Bernoulli ’ s principles to your study of immersed bodies in fl uids and the parameters associated with internal fl uid fl ow in piped systems. Finally in the fourth outcome of this unit you will apply some of the principles laid down by Boyle, Charles and Joule when you study energy transfer in thermodynamic systems. These same thermodynamic principles were used by Sir Frank Whittle when he pioneered his Jet Engine – considered by some to be the greatest invention of the twentieth century.
