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.

A small object with mass 0.200 kg moves with constant speed in a vertical circle of radius 0.500 m. It takes the object 0.200 s to complete one revolution (a) What is the translational speed of the object? (b) What is the frequency? (c) As the object passes through the lowest point in its motion, what is the direction of the acceleration of the object? upward downward The acceleration is zero and has no direction. (d) As the object passes through the lowest point of its motion, what is the magnitude of the acceleration of the object?

One popular design of a household juice machine is a conical, perforated stainless steel basket 3.30 cm high with a closed bottom of diameter 8.00 cm and open top of diameter 13.40 cm that spins at 23000 revolutions per minute about a vertical axis. Solid pieces of fruit are chopped into granules by cutters at the bottom of the spinning cone. Then the fruit granules rapidly make their way to the sloping surface where the juice is extracted to the outside of the cone through the mesh perforations. The dry pulp spirals upward along the slope to be ejected from the top of the cone. The juice is collected in an enclosure immediately surrounding the sloped surface of the cone. Pulp D Motor Spinning basket Juice spout (a) What centripetal acceleration does a bit of fruit experience when it is spinning with the basket at a point midway between the top and bottom? m/s² ---Direction--- (b) Observe that the weight of the fruit is a negligible force. What is the normal force on 1.50 g of fruit at…

A car accelerates uniformly from rest and reaches a speed of 14.8 m/s in 5.2 s. diameter of a tire is 39 cm. The Find the number of revolutions the tire makes during this motion, assuming no slip- ping. Answer in units of rev.
