GENERAL KNOWLEDGE

Detailed explanation-1: -For a given spring and other elastic objects, the extension is directly proportional to the force applied. For example, if the force is doubled, the extension doubles. This works until the elastic limit is exceeded.

Detailed explanation-2: -extension of an elastic object is directly proportional to the force applied to it. In other words: • If the force applied is doubled, the extension doubles • If no force is applied, there is no extension The graph of force against extension is a straight line through the origin, which shows a linear relationship.

Detailed explanation-3: -Hooke’s law, law of elasticity discovered by the English scientist Robert Hooke in 1660, which states that, for relatively small deformations of an object, the displacement or size of the deformation is directly proportional to the deforming force or load.

Detailed explanation-4: -71 10.1 Force-Deformation Curve makes it clear that the deformation is proportional to the applied force. Figure 1 shows the Hooke’s law relationship between the extension L of a spring or of a human bone. For metals or springs, the straight line region in which Hooke’s law pertains is much larger.

Detailed explanation-5: -Elasticity and forces are closely related because forces can cause objects to change shape, and the ability of an object to return to its original shape after being deformed by a force is related to its elasticity.
