Question
The beam shown has circular cross 1.SD section and supports a load that varies from 1,000 lb. to 3,000 lb.; it is 6" machined by AlISI 1020 steel, as 12" rolled. Determine the diameter D if r 12" 0.2D and N = 2; indefinite life. The same as Problem (5), except that the load F is steady at F = 3000 lb. and the beam rotates as a shaft.
