A structural lin that is 3 in. wide and 0.5 in. thick is to have a factor of safety of 2 relative to its yield strength of 36 Ksi. (a) Determine the maximum allowable tensile force on the bar. (b) if the link is allowed to elongate by no more than 0.05 in. prior to reaching the maximum allowable tensile force, determine the maximum length of the link.
