2. (10 pts) Determine the probability of failure of a steel tension member in a truss that supports widely varying snow loads given the following data on the loading placed on the member (Q) and the member strength (R); Q = 8,000 lbs and COV = 0.27 and R = 15,000 lbs and COV = 0.08. First solve assuming that each variable, Q and R were represented by a normal distribution and then resolve assuming that each was best represented by a log-normal distribution. 3. (5 pts) Given the information in Problem 3, determine to what strength the tension member would have to be designed to if the designer wanted a probability of failure of only 0.0001. Assume a log- normal distribution for this scenario.
