Elastic Band Force Extension Graph

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.

Elastic band force extension graph. The graph shows the behaviour of a length of wire in the region for which the substance obeys hook s law. This works until the limit of proportionality is exceeded. Non linear extension and plastic. Click here to get an answer to your question the diagram shows a force extension graph for a rubber band.

Hooke s law says that the extension of an elastic object is directly proportional to the force applied to it. This works until the limit of proportionality is exceeded. To the force applied. When an elastic object is stretched beyond its limit.

The minus sign shows that this force is in the opposite direction of the force that s stretching or compressing the spring. The gradient of a force extension graph before the elastic limit is equal to the spring constant. Deformation can be seen above the elastic limit. The rubber band will get heated if it is stretched and released which of these can be deduced from the graph.

Rubber does not return to its original length after it is stretched iii. Of a material or a spring is its increase in length when pulled. Consider the following statements. For example if the force is doubled the extension doubles.

To the force applied. The variables of the equation are. It will be easier to compress this rubber then expand it ii. When an elastic object is stretched beyond its limit.

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.
