I'm interested in knowing the necessary diameter of a steel and Al rod 25" long and needing to bear a load of 250 pounds

Welcome to the Forum,

Will the load be in tension or compression? Or are you considering a angled load? Will the load be dynamic or static?

Dynamic flex load near center of ~20" or Al rod. both ends are fixed.
