Experiment 6: General Physics Laboratory - Youngs Modulus - Stress is the force per unit area causing the deformation. - Strain is a measure of the amount of deformation. - The elastic modulus is the constant of proportionality between stress and strain. - For sufficiently small stresses, the stress is directly proportional to thestrain. - The constant of proportionality depends on the material being deformed andthe nature of the deformation. Section 5.3 - The elastic modulus is called Youngs modulus. - Y = Youngs modulus - F/A = Stress - L/L = Strain Additional Points: - SI unit of stress is Pascal (Pa). - 1 Pa = 1 N/m². - The tensile strain is the ratio of the change in length to the originallength. - Strain is dimensionless. Properties of Youngs Modulus: - Youngs modulus applies to a stress of either tension or compression. - Experiments show: - The change in length for a fixedexternal force is proportional to the original length. - The force necessary to produce agiven strain is proportional to the cross-sectional area. Elastic Limit: - It is possible to exceed the elastic limit of the material. - Beyond this point, stress and strain are no longer directly proportional. - The material ordinarily does not return to its original length aftersurpassing the elastic limit. - If stress continues, it surpasses its ultimate strength. - The ultimate strength is the greatest stress the object can withstand withoutbreaking.
