A straight rod of solid circular cross section is made of steel (E = 30 × 106 psi) and subject to a tensile load P. Both the load and the length of the rod are normally distributed random variables  Develop an analytical expression to select the cross-section area A of the rod such that the probability of the rod stretching more than 0.5" under the load is 1/100. Assume that
