MAS280 Mechanics and Fluids
|Semester 2, 2021/22||10 Credits|
|Lecturer:||Dr Ashley Willis||Timetable||Reading List|
This course extends the principles of Newtonian mechanics from the mechanics of particles to the mechanics of three-dimensional (3D) bodies, first to the motion of solids, then to the motion of fluids (e.g. air and water).Mathematically, this course develops the vector calculus, the essential tool for describing a 3D world. The suffix notation and the Einstein summation convention are introduced as an alternative notation for the calculus. Properties of the vector gradient operator are first seen as a natural description for potential forces. For more advanced use of the vector calculus, the most intuitive setting to comprehend its properties is through the study of fluid motion. Topics include 3D extensions of the work-energy principle, planetary and satellite motion, elements of the motion of rigid bodies, and the motion of inviscid (frictionless) fluids.
