Hooke's Law

HOOKE'S LAW within elastic limit Stre- SS is circcily proportional to strain. stress & strain stress = Exstrain E = stress strain E = modulus of elasti- city craph; x strain

slope of stress strain gr ph gives modulus of Cla. S sticity. Fromgraph, tano = stress strain tone= modulus of elasti- city. tane = E
