Document Summary
): the internal force per unit area which results by applying an external load or force. Same formula as pressure, but stress is internal. How object responds to the load applied. Ex the cn tower, the top will sway if it is very windy and this needs to happen so that it can deal with the stress from the environment. What is a material used in sport that is very flexible in one direction but stiff and brittle in another. Ex a hockey stick, made of composite or carbon fiber. Longitudinal strain: divided by its original size. Pull object apart or push it together. Strain = deformation how much change in shape is occurring in order for it to endure the stresses/loads. Initially get a straight line called young"s modulus describes the resistance to deformation of the material. Materials such as concrete, glass and wood do not deform.
