A square yellow-brass bar must not stretch more than 2

Mechanical Engineering Jan 26, 2021

A square yellow-brass bar must not stretch more than 2.5 mm when Problems 73
it is subjected to a tensile load. Knowing that E 5 105 GPa and that
the allowable tensile strength is 180 MPa, determine (a) the maximum
allowable length of the bar, (b) the required dimensions of the
cross section if the tensile load is 40 kN.
