Elastic Band Force Extension Graph

Hooke s law says that the extension of an elastic object is directly proportional to the force applied to it.

Elastic band force extension graph.

This works until the limit of proportionality is exceeded. Rubber does not return to its original length after it is stretched iii. When an elastic object is stretched beyond its limit. F which represents force k which is called the spring constant and measures how stiff and strong the spring is and x is the distance the spring is stretched or compressed away from its equilibrium or rest position.

Non linear extension and plastic. Of a material or a spring is its increase in length when pulled. To the force applied. If you repeatedly stretch and release a rubber band you can feel the effect of heating caused by hysteresis.

When an elastic object is stretched beyond its limit. P and q represent a p applied force q extension b p extension q applied force c p extension q stored elastic energy d p stored elastic energy q extension. The rubber band will get heated if it is stretched and released which of these can be deduced from the graph. It will be easier to compress this rubber then expand it ii.

This works until the limit of proportionality is exceeded. The graph shows the behaviour of a length of wire in the region for which the substance obeys hook s law. Under stress it was shown that the energy absorbed or released by a material is represented by the area between the curve and the extension axis of a force extension graph. The gradient of a force extension graph before the elastic limit is equal to the spring constant.

To the force applied. For example if the force is doubled the extension doubles. Click here to get an answer to your question the diagram shows a force extension graph for a rubber band. Consider the following statements.

Deformation can be seen above the elastic limit.
