The ship at A has just started to drill for oll on the ocean floor at a depth of h-4000 ft. Knowing that the top of the 8-in.-diameter steel drill pipe (G-11.2 x 106 psl) rotates through two complete revolutions before the drill bit at B starts to operate, determine the maximum shearing stress caused in the pipe by torsion. The maximum shearing stress caused in the pipe by torsion is ksl.
