9.A steel rod of diameter 0.125" is bent into the shape shown, and fixed at one end. Ifa vertical force F = 2.0 lb is applied at the other end, what is the vertical deflection there? Use E= 30 Msi, and S, = 35 ksi. %3D 118 A. 14x10 in B.94x10 in C 64x10 in D. Don't really know, since the rod yields when F is applied E. None of the above 59 45°

vi)  Using Macauley’s method, determine the deflection of the member at the locations where the 25 kN, 20 kN and 50 kN point loads are applied. Comment on how the maximum deflection of the member could be determined. Material properties for steel: Maximum allowable tensile stress = 750 MN/m2 Maximum allowable torsional shear stress = 375 MN/m2 Young’s Modulus of elasticity = 205 GN/m2Modulus of rigidity = 81 GN/m2Poisson’s ratio = 0
