A cylindrical reservoir with a radius R is hang on a string (so it may freely rotate). The reservoir has two nozzles at its bottom part. The nozzles are oriented tangentially to the reservoir surface. They exert thus a torque giving rise to rotations about the vertical axis. Find the angular velocity of the reservoir rotation. Assume that the reservoir radius is much larger than that of the nozzles. The separation between the nozzles is 2L

A cylindrical reservoir with a radius R is hang on a string (so it may freely rotate). The reservoir has two nozzles at its bottom part. The nozzles are oriented tangentially to the reservoir surface (see Figure 1). They exert thus a torque giving rise to rotations about the vertical axis. Find the angular velocity of the reservoir rotation. Assume that the reservoir radius is much larger than that of the nozzles. The separation between the nozzles is 2L. (2P)...
an 8kg flywheel of radius r is initially at rest. assume the radius of the gyration kG= 0.12m and the radius of the flywheel r = 0.125m. an object B also of mass 8 kg is attached to a cord that is wrapped around a periphery of the flywheel. the fly wheel starts to rotate clockwise with angular velocity. the rotation is resisted by a constant frictional torque mf in the bearing 1Nm. use the work energy principle to determine...
A string is wrapped around a uniform solid cylinder of radius r, as shown in (Figure 1). The cylinder can rotate freely about its axis. The loose end of the string is attached to a block. The block and cylinder each have mass m. Part A. Find the magnitude α of the angular acceleration of the cylinder as the block descends. Express your answer in terms of the cylinder's radius r and the magnitude of the acceleration due to gravity...
A child pushes her friend (m = 25 kg) located at a radius r = 1.5 m on a merry-go-round (rmgr = 2.0 m, Imgr = 1000 kg*m2) with a constant force F = 90 N applied tangentially to the edge of the merry-go-round (i.e., the force is perpendicular to the radius). The merry-go-round resists spinning with a frictional force of f = 10 N acting at a radius of 1 m and a frictional torque τ = 15 N*m...
