A 100-kg solid cylindrical disk, 800 mm in diameter, is to be raised over a 200-mm obstruction. A cable is wrapped around the disk and pulled with a constant horizontal force T as shown. Knowing that the disk rotates about the corner of the obstruction and that the angular velocity of the disk is 1 rad/s when it has reached the top of the obstruction, determine the force T.

One engineer, Chersiphron, tried several different techniques to do this. One method was to cut pivot holes into the ends of the stone and then use oxen to pull the column.
