Extracted text: 5. A solid shaft produced from the 1045 steel in the figure must be 240 cm long and must survive continuous operation for 1.5 YEAR with an applied load of 6000 N. The shaft makes one revolution per minute during operation. What must be the diameter of the shaft that will satisfy these requirements? What must be the diameter if the shaft would work without fracture indefinitely? The maximum stress acting on this type of shaft is o = 10.18 L*F/d³
