A uniform disk turns at 2.7 rev/s around a frictionless central axis. A nonrotating rod, of the same mass as the disk and length equal to the disk's diameter, is dropped onto the freely spinning disk(Figure 1) . They then turn around the spindle with their centers superposed. What is the angular frequency in rev/s of the combination?
A uniform disk turns at 3.6 rev/s around a frictionless central axis.

The rod AB shown in Figure 3 has a constant angular rotation of 5 rad/s and is advancing upward along the axis of the bolt at a constant rate of 10 mm/s. Express the velocity and acceleration of point A on the rod in terms of its cylindrical components. 10 mm/s 6 = 5 rad/s 100 mm Figure 34
In the figure below, the bar has moment of inertia 0.4 Kgm^2 and is spinning clockwise, around an axis passing through the depicted point and perpendicular to the plane of the page, with angular speed of 10 1/s (or 10 rad/s). The 4 N depicted force, generates a constant torque (which slows down the bar rotation) for 2 seconds. Calculate the magnitude of the applied torque. Calculate the angular speed of the torque at t = 2 s.
The contraption below is made of a slender rod and a circular disk welded to its end. There is a torsional spring with a stiffness k = 1000 N-m/rad attached to the rod at the pin support, O. A projectile is traveling from right to left and strikes the side of the disk and embeds. The pendulum is initially at rest. The rod has a mass of 10 kg and the disk has a mass 20 kg. The projectile has...
Part A The wheel is spinning about shaft AB with an angular velocity of Wg = 10 rad/s, which is increasing at a constant rate of 2 = 6 rad / s, while the frame precesses about the z axis with an angular velocity of Wp = 12 rad/s, which is increasing at a constant rate of . = 3 rad / s. Determine the velocity of point located on the rim of the wheel at this instant. Express your...
A rod of length L and negligible mass is attached to a uniform disk of mass M and radius R (see figure below). A string is wrapped around the disk, and you pull on the string with a constant force F. Two small balls each of mass m slide along the rod with negligible friction. The apparatus starts from rest, and when the center of the disk has moved a distance d, a length of strings has come off the...
