The A992 structural steel bar and a 2014-T6 aluminium bar shown below are secured to rigid supports at ends A and B and are connected together by a 1" diameter tool steel pin in double shear. The pin slides freely into place at room temperature. Determine the shearing stress on the pin caused by a 60 degree F drop in temperature and comment on its ability to carry the applied load.
