A square yellow-brass bar must not stretch more than 3 mm when it is subjected to a tensile load of 34 kN. Given: E = 105 GPa and that the allowable tensile strength is 108 MPa, determine (a) The allowable side length of the cross-section (b) Is the allowable value a maximum or a minimum? Why? (c) The allowable length of the bar (d) Is the allowable length a maximum or a minimum?
