MODEL RELEASED. Schoolgirl investigating elasticity. Weights are attached to a hanging rubber band. The student measures the extension resulting from this using a ruler and a set square. Up until a point known as the elastic limit,materials will behave elastically; that is,their extension will be proportional to the force applied. This is known as Hooke's Law | |
