Hooke's Law is a more universal concept that the simple statement 'Force=constant times force'? All materials obey Hooke's Law over a certain range of conditions. This is because all solids have a Young' modulus \[Y\] , defined as...

Elastic strings are similar to springs. Both strings and springs obey Hooke's Law when being extended, but when being compressed, there is no tension in the string while the spring experiences a force tending to increase the length. (Springs obey...

Three graphical concepts are very useful – the intercepts (particularly the y – intercept), the gradient of the graph at a point and the area under the graph. The intercept is a point on an axis where the graph crosses. If the graph is a line and the y...

The tension in a stretched string is usually expressed in terms of it's modulus of elasticity This is in fact an expression of Hooke's Law – Force is proportional to extension. Suppose that a string of length l is stretched between two points A and B....
