Question
Determine the force P necessary to close the gap at the steel post.
The steel post is 2 inch x 2 inch square and 8 in high. The aluminum alloy bar is 1.5 inch
wide by 1 inch thick and 20 in long. The horizontal bar is considered rigid as are the
loading caps at the steel post. The modulus of elasticity for the steel is 30,000 ksi, that
of aluminum is 10,000 ksi. The yield stress for the steel is 36 ksi, that of the aluminum is
40 ksi.
