Hooke's Law lecture diagram. English scientist Robert Hooke (1635-1703) for his lecture on springs. Hooke's Law states that the extension of a spring (right) is directly proportional to the load placed on it, providing the spring's elastic limit has not been reached. This law has great importance in engineering and physics, and can be broadly applied to many materials. Hooke first stated this law in 1660, publishing his theory in 1678. This is figure 3 from Hooke's 'Lectures de Potentia Restitutiva' (1678).
