Problem1: The entire composite shaft shown in the following figure is manufactured using steel with a modulus of rigidity of 80 GPa. The dimensions of the composite shaft are included in the figure. Unknown torques of equal magnitude T are applied to the two ends A and D. a. If the steel material has the maximum allowable shear stress of 75 MPa, determine the maximum allowable torque T that can be applied to the shaft. b. Once you have found the maximum allowable T in part a, use that value to determine the angle of twist of end A relative to the end D.

Can we calculate true strain values at point M and F using ɛT = ln(1+ɛ) ? If no, why?

A tensile test is performed to determine the strength constant C and strain-rate sensitivityexponent m for a certain metal. The temperature at which the test is performed is 500ºC. At astrain rate of 12/s, the stress is measured at 160 MPa, and at a strain rate of 250/s, the stress is300 MPa. Determine C and m.

Provide 3-dimensional Equation for Hooks Law for strain and for Shear?

Determine the single uniformly distributed load in the x direction that would produce the same deformation in the y direction as the original loading for a given rectangular block with the following data: 4 inches long in the x direction, 2.5 inches long in the y direction, and 3.5 inches long in the z direction. The block is subjected to a triaxial loading of three uniformly distributed forces as follows: 52 kips tension in the x direction, 68 kips compression in the y direction, and 49 kips tension in the z direction. Given v = 0.28 and E = 30 x 10° psi, O a. 265.23 kips O b. 255.80 kips Oc 220.25 kips O d. 246.56 kips

For some metal alloy, a true stress 345 MPa (50040 psi) produces a plastic true strain of 0.02. How much will a specimen of this material elongate when a true stress of 418 MPa (60630 psi) is applied if the original length is 500 mm (19.69in) ? Assume a value of 0.22 for the strain- hardening exponent, n
