Robert Hooke studied the uniaxial force required to extend springs and long straight wires and found it ... been formalized into the stress/strain relationship known as Hooke's Law: ...

Purpose: To investigate experimentally the extension of a spring and how it is related to the applied force, and recall that the extension of a spring is directly proportional to the force applied ...

Record each stretching force in N and the corresponding length of the spring. The extension is the new length minus the unloaded length. Figure caption, Graph showing Hooke's Law, force is plotted ...

He is known to many school students for his law of elasticity, which states that strain on a spring is proportional to stress. Hooke worked with Robert Boyle to make the first air pump ...
