Do not round intermediate calculations. Give your final answer(s) to three significant figures. A square yellow-brass bar must not stretch more than 4.6 mm when it is subjected to a tensile load. Knowing thatE -105 GPa and that the allowable tensile strength is 164 MPa, determine (a ) the maximum allowable length of the bar, (b) the required dimensions, in mm, of the cross section if the tensile load is 31 kN. (a) The maximum allowable length of the bar...
