Plot the function y = x62 - x + 2/x^2 + x + 2 for -10 lessthanorequalto x lessthanorequalto 10 b). The magnitude M, on the Richter scale, of an earthquake is given by: M = 2/3 log E/10^4.4 Where E is the energy in Joules released by the earthquake. Make a plot of E (y-axis) versus M (x-axis) for 3 lessthanorequalto M lessthanorequalto 8. Use a logarithmic scale for E and a linear scale for M. Label the axes and add to the plot. c) A simply supported beam is loaded as shown. The shear force V and bending moment M as a function of x are given by the following equations: V(x) = 400 - 200x lb M(x) = - 100x^2 + 400x lb-ft for 0 lessthanorequalto x lessthanorequalto 8 ft. V(x) = -1, 200 lb, M(x) = -1, 200 x + 6, 400 lb-ft for 8 lessthanorequalto x lessthanorequalto 12 ft V(x) = -250x + 5,000 lb, M(x) = -125 (x - 12)^2 + 2, 200x + 32,000 lb-ft for 12 lessthanorequalto x lessthanorequalto 20 ft Plot the shear force and the bending moment as a function of x (two figures on one page such that the shear force diagram is displayed above the bending moment diagram)
