What is Young's modulus, how is it calculated, why is steel so much stiffer than aluminium, and how do you measure it in the lab? Formulas, unit conversions, a calculator, a materials table and the full Searle's apparatus experiment.
What does Hooke's law state, where does it stop holding good, and how do you verify it in the lab? A complete guide with the F = −kx formula, stress-strain curve, Young's modulus, and a step-by-step spring experiment.
