Problem 2 (35 points) A thin walled tube is subjected to an externally applied tensile load P of 100 N and torque T of 150 N.m as shown in the figure. The tube has an outer diameter Do=90 mm, and an inner diameter Di = 80 mm. The tube is fabricated from a unidirectional lamina whose fibers are at 45" off the tube axis. fo A) Compute the stresses in the walls of the tube. B) Determine the effective elastic properties of the composite lamina used to make the tube. That is determine E₁, E2, V₁, G12 C) Determine the strains observed along the fibers and perpendicular to the fibers. D) Using maximum strain theory, determine if this tube will fail or not. (use the failure strengths defined in the table included in problem 1) The properties of the fibers and matrix used in the composite lamina are used below Fiber properties: Matrix properties: E = 600 MPa, v = 0.2, G = 250MPa E = 4 MPa, v = 0.4, G = 1.4MPa The fiber volume fraction is equal to the sum of the digits in your university ID divided by 100. For example, if your ID is 00012345, then your fiber volume fraction is 15/100-0.15
