- In a standard tensile strain test, a 20 mm diameter aluminum rod is subjected to a tensile force of P = 30KN. If μ = 0.35 (Poisson's ratio) and E = 70 GPa (Young's modulus), determine: a) The elongation of the rod in a calibrated length of 150 mm and b) The change in the diameter of the rod19. A force of 5000N is applied outwardly to each end of a 5.0-m long rod with a radius of 34.0 cm and a Young's modulus of 1.25 x 10°8 N/m^2. The elongation of the rod is: * A. 0.0020mm B. 0.0040mm C. 0.14mm D. 0.55mm O E. 1.42mmcan someone explain how this is the answer? i got 5.2*10^3 but the answer is 8066.888? please explain how!
- Two rods are identical in all respects except one: one rod is made from aluminum (Young's modulus 6.8 x 1010 N/m²), and the other from tungsten (Young's modulus 1.7 x 1011 N/m²). The rods are joined end to end, in order to make a single rod that is twice as long as either the aluminum or tungsten rod. What is the effective value of Young's modulus for this composite rod? That is, what value Ycomposite of Young's modulus should be used in Equation 10.17 when applied to the composite rod? Note that the change ALComposite in the length of the composite rod is the sum of the changes in length of the aluminum and tungsten rods.if Vf=0.8 (volume fraction fiber) longitudinal modulus=? poisson's ratio=? in-plane shear stress=?Determine the magnitudes of the force Rand couple Mexerted by the nut and bolt on the loaded bracket at O to maintain equilibrium. 110 mm 170 mm 25 2.9 kN 2.9 kN 54 220 mm Answers: R = kN M = i kN-m
