Problem 14.47) Disks A, B, C, and D can ślide freely on a frictionless horizontal surface. Disks B, C, and D are connected by light rods and are at rest in the position shown when disk B is struck squarely by disk A which is moving to the right with a velocity vo 12 m/s. The masses of the disks are m,-m,-mc - 7.5 kg, and m 15 kg. Knowing that after impact disks A and B are bound togetherV)...

The Geneva mechanism shown is used to provide an intermittent rotary motion of disk S. Disk D weighs 2 lb and has a radius of gyration of 0.9 in. and disk S weighs 6 lb and has a radius of gyration of 1.5 in. The motion of the system is controlled by a couple M applied to disk D. A pin Pis attached to disk D and can slide in one of the six equally spaced slots cut in disk...

Problem 4. (25 points) The thin disk below turns on a massless arm B by way of a smooth bearing that keeps the axes of D and B aligned. The arm is hinged to the shaft driven at a constant angular speed 12 by a motor. The system is set up so that the arm is horizontal when the disk contacts the ground as shown. Assuming the disk of mass m rolls without slipping, find the force reactions and the...

In a manufacturing process, disks are moved from level A to level B by the-lifting arm shown. The arm starts from level A with no initial velocity, moves first with a constant acceleration a, as shown, then with a constant deceler- ation ag, and comes to a stop at level B. Knowing that the coefficient of static friction between the disks and the arm is 0.30, determine the largest allowable acceleration a, and the largest allowable deceleration a2 if the...

Figure 12 shows two disks A & B rotating in the same direction. Disk A has a mass of 2.00 kg, a radius of 0.200 m, and an initial angular speed of 50.0 rad/s. Disk B has a mass of 4.00 kg, a radius of 0.100 m, and an initial angular speed of 200 rad/s. The disks are pushed toward each other with equal and opposite forces acting along the common axis. Find the common angular speed after the disks...

Two disks are mounted (like a merry-go-round) on low-friction bearings on the same axle and can be brought together so that they couple and rotate as one unit. The first disk, with rotational inertia 3.25 kg m2 about its central axis, is set spinning counterclockwise (which may be taken as the positive direction) at 181 rev/min. The second disk, with rotational inertia 7.95 kg.m2 about its central axis, is set spinning counterclockwise at 879 rev/min. They then couple together. (a)...

The disk shown above has radius 2.50m and mass of 10.0kg. It has an angular velocity of 9.50 rad/s at t 0s about its center O, moving in the CounterClockwise direction. It also experiences a Clockwise angular acceleration of 1.00 rad/s2. a) What is the disk's moment of inertia? b) What Kinetic Energy does the disk possess at t-0.00s and at t-6.00s? c) How long does it take for the disk to stop rotating momentarily? d) What is the disks'...
