Problem 4 (MATLAB SIMULATION): The impact factor of moving trucks on bridges can be modeled by a lognormal distribution with a mean value and standard deviation of ux = 1.45, and x = 0.2, respectively. The impact load would cause damage to the bridge, if it exceeds 1.75. Find the probability that a bridge will be damaged due to impact loading. MATLAB code must calculate the mean and standard deviation for Y, and use lognormal random number generation to simulate for the load. Plot histogram and output the results of Matlab's calculation of the probability.
