5. The total maximum load, T, on a support beam is composed of the dead load, D, and the live load, L; hence, T = D+L. The means and standard deviations of the live (L) and dead (D) loads are (1) HL=600 HD = 2800 tons, OL=80 tons tons, op = 400 tons (a) Find the mean and standard deviation of the total maximum load. Assume that the live load and the dead load are uncorrelated. (b) Find the probability that T exceeds 3500 tons assuming the L and D are normally distributed.
