Q1: Micromechanics (20%) (i) On April 1$^{st}$, your friend, Vladimir, claims that he could make a unidirectional long fiber composite with an $E_1 = 350 GPa$, using high-modulus carbon (HMC, $E = 450 GPa$) in an epoxy matrix ($E = 3 GPa$). Based on your professional judgment, would this be possible? Show your work and explain why or why not. (ii) A uniaxial long fiber composite is made from the aforementioned HMC and epoxy. The elastic modulus of the composite in the direction of the fibers is measured to be 230 GPa. Calculate an estimate for the TRANSVERSE elastic modulus of the composite using both the IROM and Halpin-Tsai models, and concisely comment on the difference between the results from IROM and Halpin-Tsai models.

1. A steel bar with circular cross section of 20 mm initial diameter was subjected to tensile force. The bar's diameter decreases by 2ยตm. If the strain was elastic and knowing that the steel Young's modulus and Poisson's ratio are 200 GPa and 0.3 respectively, calculate the applied force 2. The following figure shows the curves from fatigue tests on 3 materials under the same conditions a) Can you determine the endurance limit of Cu? If yes, determine its value. b) If a circular section shaft of 8 mm diameter made of Cu is attached to a motor running at 2000 rpm and subject to a force of 5 kN, calculate the life of the shaft in terms of the number of hours. Stress amplitude (MPa) 600 500 400 Steel 300 Al 200 Cu 100 0 1,E+00 1.E+01 1.E+02 1.E+03 1.E+04 1.E+05 Number of cycles (1000.N) Note that on the X axis 1.E+00 = 1000 cycles and 1.E+01 = 1000x10ยน and so on
