A flat bar is 3/8 inches thick and has a centrally located drilled hole of diameter D. The bar is subjected to a 4,000 lb tensile load. Compute the maximum tensile stress adjacent to the hole. a) If the bar is 2 inches wide and D=0.25 inches b) If the bar is 2.5 inches wide and D=0.5 inches c) If the bar is 3 inches wide and D=1.00 inches Answers: a) = 15,969.5 psi (using k=2.62) b) = 13,066.7 psi (using k=2.45) c) = 12,000 psi (using k=2.25)
