A beam of circular CTOSS- section is subjected to pure bending moment M and the bending stresses are given by the following equation: 32AM where d is the diameter of the beam. It has been observed that the diameter (d) of the beam is a normally distriluted random variable with a mean of 50 mm and a standard deviation of 0.125 mm. The bendding moment (M) is also a normally distributed random variable with a mnean of 1750 N-m and a standard deviation of 150 N-m. Determine the mean and standard dleviation of the corresponding bending stress variable (o). Comment on the analvsis.
