In mechanics of materials. Young's modulus is an important material property. The young's modulus E usually decreases as temperature T increases. The table below lists the measured Young's moduli of a metal under various temperatures in a series of uniaxial tensile tests. Plot Young's Modulus vs Temperature using the data in the table. Then do curve fitting with a linear (degree n=l), quadratic(n=2) and cubic equation(n=3). Mention the equations that you get from each of the fitting and comment on the accuracy of each fitting.
