Please answer all parts of the question, thank you!

1 ... The L-shaped part below is pinned at the left, roller supported on the right and deflected with a displacement, v as shown. The deflection is applied cyclically from O to a maximum value of 0.05 inches. The part is required not to yield and to have effectively infinite fatigue life. (a) Calculate the stiffness, k = P/V in terms of the dimensions, L1, L2,h, b and the elastic modulus, E. (b) Calculate the maximum tensile stress in terms of the dimensions and the load, P. (c) Assume that the part is made of steel and numerically calculate the stiffness, in lbf/in, the load in lbf when the displacement, v = 0.05 inches, and the maximum stress in ksi. (d) Select a steel that will be suitable for this application. The application requires a yield safety factor of Xn = 1.4 and fatigue life of 107 cycles (e) Write out all the steps in your analysis (i.e. F.B.D., ...) as well as the assumptions that you either explicitly make or that are implicit to the analysis. (f) Which dimensional parameter has the strongest effect on the stiffness and maximum stress? V L 2 L, thickness = h, width into board = b. Dimensions are L1 = 1, L2 = 0.3, h = 0.0179, and b = 0.5 inches. 1 ... The L-shaped part below is pinned at the left, roller supported on the right and deflected with a displacement, v as shown.
