The shaft shown in the figure is machined from AISI 1040 cold-
drawn steel. The shaft rotates at 1600 rpm and is supported in rolling
bearing at A and B. The applied forces are Fj=4.8 kN and F=9.6kN.
Assume that the bending stress is completely reversed.
(a) Draw bending-moment diagram and calculate the moment at the
following four points (0-@). And then, calculate the maximum
reversing stress at the critical position which the failure is expected.
