Elastic Band Force Extension Graph

Consider the following statements.

Elastic band force extension graph.

The minus sign shows that this force is in the opposite direction of the force that s stretching or compressing the spring. Deformation can be seen above the elastic limit. When an elastic object is stretched beyond its limit. Rubber does not return to its original length after it is stretched iii.

For example if the force is doubled the extension doubles. Non linear extension and plastic. The gradient of a force extension graph before the elastic limit is equal to the spring constant. This works until the limit of proportionality is exceeded.

If you repeatedly stretch and release a rubber band you can feel the effect of heating caused by hysteresis. Hooke s law says that the extension of an elastic object is directly proportional to the force applied to it. 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.

For example if the force is doubled the extension doubles. The variables of the equation are. It will be easier to compress this rubber then expand it ii. 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 graph shows the behaviour of a length of wire in the region for which the substance obeys hook s law. The rubber band will get heated if it is stretched and released which of these can be deduced from the graph. 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. To the force applied.

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