A split-ring clamp-type shaft collar is shown in the figure. The collar is 2 in OD by 1 in ID by ½ in wide. The screw is designated as ¼ -28 UNF. The relation between the screw tightening torque T, the nominal screw diameter d, and the tension in the screw Fi is approximately T = 0.2 Fi d. The shaft is sized to obtain a close running fit. Find the axial holding force Fx of the collar as a function of the coefficient of friction and the screw torque.
