Learning on ScreenMechanics Through Applications (8 Parts)
- Synopsis
- 1: Describes how the principles of Newtonian mechanics are used to reconstruct traffic accidents from the debris and marks on the road. Shows how speeds of vehicles were calculated using momentum exchange, equations of motion, and force due to friction.
2: Describes the mathematics behind accident reconstruction when a vehicle has performed a curved skid. Illustrates critical speed, friction, motion in a circle, and Newton’s laws of motion.
3: Discusses applied forces, e.g. weight, traffic, snow, wind, producing static equilibrium in frameworks, tension adn compression in members, and the method of resolution in the vertical and horizontal directions. Lattices as force systems are illlustrated using film from a session showing destructive testing of laboratory-built bridges.
4: Compares lattice or truss bridges and girder bridges which carry bending and shear loads as well as direct forces. Shows the relation between shearing force and bending moment and describes their relation to force systems and elastic behaviour. Shows Alton Towers’ ‘Corkscrew’ ride.
5: Behaviour and applications of different types of engineering materials are studied in design. Develops the mathematical modelling technique of scoring. The automobile is taken as an example of compromise in design.
6: Different forms of energy, including potential, kinetic, chemical, electrical. Measurement of energy. The first law of thermodynamics. Observes types of energy with a car driven up an inclined slope.
7: Explores reversible and irreversible energy processes, energy efficiency, order and disorder, the second law of thermodynamics. Illustsrations are drawn from radiant heating, the sun, and man-made heaters (inverse-square law).
8: Describes factors in leisure-park ride maintenance and discusses the principles of mechanics involving gravity and friction. - Language
