Greek engineers had the unenviable task of moving largecolumns from the quarries to the city. One engineer, Chersiphron, tried several different techniques to do this. Onemethodwas to cut pivot holes into the ends of the stone andthen use oxen to pull the column. The 5-ft diameter columnweighs 14,000 lbs, andthe team of oxen generates a constantpull force of 2,000 lbs on the center of the cylinder, G. Knowingthat the column starts from rest and rolls without slipping, determine:(a) the velocity of its center, G,after it has moved7ft, and (b) the minimum static coefficient of friction that will keepit from slipping.
