4-51. The press consists of two rigid heads that are held together by the two A-36 steel 1 1/2-in.-diameter rods. A 6061-T6 solid aluminum cylinder is placed in the press and the screw is adjusted so that it just presses up against the cylinder. If it is then tightened one-half turn, determine the average normal stress in the rods and in the cylinder. The single-threaded screw on the bolt has a lead of 0.01 in. NOTE: The lead represents the distance the screw advances along its axis for one complete turn of the screw. *4-52.
