Failure analysis of a 2" OD solid 6063 aluminum round bar I have a 6 foot piece of 2" OD solid 6063 aluminum bar that is supported at both ends. Hanging from the center is a 5000 pound weight. What techniques and equations would be used to determine if the aluminum bar will successfully bear this load? This setup is going to be used as an anchor point for fall arrest protection on a communications tower. Any help anyone can provide would be appreciated.
