Science for Materials 1

Synopsis: 1: Introduces some fo the properties exhibited by fluids and materials which under conditions behave like a fluid: flow and viscostiy; buoyancy; hydrostatic pressure; and surface energy. Also covers extrusion, sand moulding and injection moulding.
2: How fast can a 38-tonne lorry travel up a 1-in-20 hill? Observations on the M1 motorway lead to the idea of power as the rate of doing work and later - as the complexity increases - using forces. Applies Newton’s Second Law and Hooke’s Law to analyse the motion of a mass bobbing on a spring.
3: The second law of thermodynamics: uses the analogy of balls on a snooker table to introduce the idea of entropy. A series of changes is presented, with the object of demonstrating that each change is in accord with the law.

Notes: NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
