Talk:A-level Physics/Forces and Motion/Deformation of solids

Specification
From the OCR GCE Physics A specification. Tick with &#10004; when you feel each part of the specification has been covered. Try not to add much more than what is in this list as it would not appear in the exam anyway. Use links to wikipedia for more depth in a topic.


 * 1) Appreciate that deformation is caused by a pair of forces and that, in one dimension, the deformation can be tensile or compressive.
 * 2) Describe the behaviour of springs and wires in terms of load, extension, Hooke’s law and the spring constant.
 * 3) Define and use the terms elastic limit, stress, strain, and the Young modulus.
 * 4) Describe an experiment to determine the Young modulus of a metal in the form of a wire.
 * 5) Distinguish between elastic and plastic deformation of a material.
 * 6) Deduce the strain energy in a deformed material from the area under the force-extension graph.
 * 7) Demonstrate knowledge of the force-extension graphs for typical ductile, brittle and polymeric materials, including an understanding of ultimate tensile stress.
