Question: A solid bar of circular cross section (diameter d) has a hole of diameter d/5 drilled laterally through the center of the bar (see figure).

A solid bar of circular cross section (diameter d) has a hole of diameter d/5 drilled laterally through the center of the bar (see figure). The allowable average tensile stress on the net cross section of the bar is Ïƒallow.
(a) Obtain a formula for the allowable load Pallow that the bar can carry in tension.
(b) Calculate the value of Pallow if the bar is made of brass with diameter d = 1.75 in. and Ïƒallow = 12 ksi.
