Elastic Band Force Extension Graph

To the force applied.

Elastic band force extension graph.

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. 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.

This works until the limit of proportionality is exceeded. The gradient of a force extension graph before the elastic limit is equal to the spring constant. 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.

Non linear extension and plastic. For example if the force is doubled the extension doubles. Hooke s law says that the extension of an elastic object is directly proportional to the force applied to it. 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. Consider the following statements. If you repeatedly stretch and release a rubber band you can feel the effect of heating caused by hysteresis. Click here to get an answer to your question the diagram shows a force extension graph for a rubber band.

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. 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. Deformation can be seen above the elastic limit. To the force applied.

The variables of the equation are.
