You are to design a rotating cylindrical axle to lift 7.7-N buckets of cement from the ground to a rooftop 3.8 m above the ground. The buckets will be attached to a hook on the free end of a cable that wraps around the rim of the axle; as the axle turns, the buckets will rise. If instead the axle must give the buckets an upward acceleration of 6.5 m/s? with a steady velocity of 3.2 cm/s turning at 3.1 rpm, what should the angular acceleration (rad/s2) of the axle be?

A man stands on a merry-go-round that is rotating at 2.5 rad/s. If the coefficient of static friction between the man’s shoes and the merry-go-round is s=0.5 , how far from the axis of rotation can he stand without sliding?
At the local playground, a 21-kg child sits on the right end ofa horizontal teeter-totter, 1.8 m from the pivot point. On the leftside of the pivot an adult pushes straight down on the teeter-totterwith a force of 151 N. In which direction (clockwise or counterclockwise) does the teeter-totter rotate if the adult applies the forceat a distance of (a) 3.0 m, (b) 2.5 m, or (c) 2.0 m from the pivot?
A box is suspended from a coil of rope on a pulley of radius (0.54m) and rotating at a constant angular velocity (1.6rad/s) to lift it up. - Calculate the height that the box reaches after three seconds ?
In the circular motion experiment with constant acceleration performed on an air table, the mass of the disk is 100 g and the length of the rope is 100 cm. Using the graph, find the tangential velocity of the object at t=3 s in m/s. (vi=0, f=10Hz)
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.
In a popular amusement parkride, a rotating cylinder ofradius 3.00 m is set in rotationat an angular speed of5.00 rad/s, as in Figure P7.73.The floor then drops away,leaving the riders suspendedagainst the wall in a verticalposition. What minimum coefficientof friction between arider’s clothing and the wall isneeded to keep the rider fromslipping? Hint: Recall that themagnitude of the maximum force of static friction is equal tomsn, where n is the normal force—in this case, the force causingthe centripetal acceleration.
For rolling without slip, the acceration of a circular disk on an incline plane a=r(alpha) where alpha = to the angular accleration. Qn. What is the difference in acceleration with slipping vs without slipping? Also, why is there no centripetal acceleration (towards the centroid of disk) when the disk is rolling without slippage?

In an amusement park ride called ‘The Roundup’, passengers stand inside a 18-m diameter rotating ring. After thering has acquired its final speed of 14 rpm’s, it tilts into a vertical plane. Whatweight does the rider feel at the top and bottomif they have a weight of 830 N?
How fast (in rpm) must a centrifuge rotate if a particle 8.50 cm from the axis of rotation is to experience an acceleration of 120000 g's?
A block of mass m is placed on a rough surface that rotates at 15 rpm. If the body has a distance of 146 cm from the vertical rotation axis, how large must the friction coefficient be so that the body remains at rest?
In a popular amusement park ride, a rotating cylinder of radius 3.00 m is set in rotation at an angular speed of 5.00 rad/s, as in Figure P7.75. The floor then drops away, leaving the riders suspended against the wall in a vertical position. What minimum coefficient of friction between a rider’s clothing and the wall is needed to keep the rider from slipping? Hint: Recall that the magnitude of the maximum force of static friction is equal to μsn, where n is the normal force—in this case, the force causing the centripetal acceleration.
