A coder F, used to record in digital form the rotation of shaft A, Problems 171is connected to the shaft by means of the gear train shown, whichconsists of four gears and three solid steel shafts each of diameterd. Two of the gears have a radius r and the other two a radius nr.If the rotation of the coder F is prevented, determine in terms ofT, l, G, J, and n the angle through which end A rotates.FD Enr rClTABAnrllrFig. P3.43
