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...
Given that a sample of PTFE has a Young's modulus of 0.48 GPa and a bulk modulus of 2 GPa. Calculate the following: a) Poisson's ratio (v) to 3 decimal places v=
A copper (Young's modulus 1.1 x 1011 N/m2) cylinder and a brass (Young's modulus 9.0 x 1010 N/m2) cylinder are stacked end to end, as in the drawing. Each cylinder has a radius of 0.38 cm. A compressive force of F = 8600 N is applied to the right end of the brass cylinder. Find the amount by which the length of the stack decreases.
A ceramic having a porosity of 15% is found to have a Young's modulus of 35×106psi. What is Young's modulus of the fully-dense ceramic?
A composite of polycrystalline spinel (Young's modulus = 277 GPa) and aligned continuous Kevlar fibers is desired in order to increase the capacity of the spinel to withstand impact. Kevlar fibers have a tensile strength of 3.6 GPa and a Young's modulus of 125 GPa. For a desired composite with Young's modulus of 200 GPa, what is the fiber volume fraction? Use isostrain condition.
