A child's top is held in place upright on a frictionless surface. The axle has a radius of ?=3.21 mm. Two strings are wrapped around the axle, and the top is set spinning by applying ?=2.15 N of constant tension to each string. If it takes 0.770 s for the string to unwind, how much angular momentum ? does the top acquire? Assume that the strings do not slip as the tension is applied. Point P is located on the outer surface of the top, a distance ℎ=31.0 mm above the ground. The angle that the outer surface of the top makes with the rotation axis of the top is ?=15.0∘. If the final tangential speed ?t of point P is 1.45 m/s, what is the top's moment of inertia ??
The clutch system is used to transmit torque through a 2-mm-thick oil film with m = 0.38 N?s/m2 between two identical 30-cm-diameter disks. When the driving shaft rotates at a speed of 1450 rpm, the driven shaft is observed to rotate at 1398 rpm. Assuming a linear velocity profile for the oil film, determine the transmitted torque.
