Changing Shape

6.1 Changing Shape When two or more forces are applied to an object it can deform (change shape). The direction of the applied forces determine whether the…
Hooke's Law

Hooke's Law In 1678, Robert Hooke found that the extension (x) of a spring is proportional to the load (force) applied (F), provided the limit of…
Stress, Strain and the Young Modulus

Stress, Strain and the Young Modulus To compare materials independent of their dimensions, we use stress and strain. Figure 6.7: Effect of Dimensions ((a)…
Elastic and Plastic Behaviour

6.4 Elastic and Plastic Behaviour Materials behave differently under stress. Figure 6.13: Stress-Strain Graph for Metal (Graph showing linear region (Hooke's…
Elastic Potential Energy

6.5 Elastic Potential Energy (E_P) Work is done to stretch/compress a material. This work is stored as elastic potential energy. Work Done = Area under…
