Maximum allowable deflection must not exceed 0.28 inches. What is the required area based on maximum allowable deformation? (in2)A bar made of high strength low-carbon steel of GRade 50 (yield strength gauge 50 ksi) , is 0.5 inchthick and 1.2 inch wide. The ultimate tensile strength of the steel is 70 ksi. Determine the load at whichthe bar starts to yield and also determine the load when the bar is likely to fracture. Taking the originalgauge length to as 5 inches and Young’s modulus of steel as 30 x 10^6 psi, estimate the new gauge lengthwhen the specimen is stressed at 2/3 of the yield stress.
