Elastic Band Force Extension Graph

Of a material or a spring is its increase in length when pulled.

Elastic band force extension graph.

To the force applied. The graph shows the behaviour of a length of wire in the region for which the substance obeys hook s law. The gradient of a force extension graph before the elastic limit is equal to the spring constant. When an elastic object is stretched beyond its limit.

Rubber does not return to its original length after it is stretched iii. 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 variables of the equation are. To the force applied.

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. 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. For example if the force is doubled the extension doubles.

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. Deformation can be seen above the elastic limit. Consider the following statements. The rubber band will get heated if it is stretched and released which of these can be deduced from the graph.

This works until the limit of proportionality is exceeded. This works until the limit of proportionality is exceeded. The minus sign shows that this force is in the opposite direction of the force that s stretching or compressing the spring. Hooke s law says that the extension of an elastic object is directly proportional to the force applied to it.

For example if the force is doubled the extension doubles.
