A small cylinder rests on a circular turntable that is rotating clockwise at a constant speed. The cylinder is at a distance of r = 12 cm from the center of the turntable. The coefficient of static friction between the bottom of the cylinder and the surface of the turntable is 0.45. What is the maximum speed vmax that the cylinder can have without slipping off the turntable?
Consider a bug which is crawling on the surface of a turntable rotating with constant angular velocity wo. List all the forces acting on it in a system of coordinates painted on the turntable (z is perpendicular to the turntable and the rotation is around the z-axis) and the direction of each of those forces, in each of the following cases: a) when the bug is moving out from the center of the turntable along a radius at constant speed...
A turntable has a radius R and mass M (considered as a disk) and is rotating at an angular velocity W 0 about a frictionless vertical axis. A piece of clay is tossed onto the turntable and sticks d from the rotational axis. The clay hits with horizontal vel ocity component vc at right angle to the turntable’s radius, and in a direction that opposes the rotation. After the clay lands, the turntable has slowed to angular velocity W1 ....
A spinning disk is rotating at a rate of 2 rad/s in the clockwise direction as shown in the figure. What is the direction of the angular velocity vector? If the disk is slowing down at a rate of 4 rad/s2, what is the direction of the angular acceleration vector? Find the wheel's angular velocity after 2 s. Find the angle through which the wheel has turned after 2 s in radians. Find the magnitude of the velocity (speed) of...
of mass m and radius R is freely rotating at angular velocityw,spinning clockwise The moment of inertia of a disk is ImR2.) While it is rotating, someone when seen from above. ( ps a thin ring of mass m and also of radius R on top of it. When the ring lands, it is initially ot otating, but friction quickly causes it to rotate along with the disk, but the rotation of the disk slows down. a) What principle of...

The disk of radius r = 1.5 m rolls without slipping on the incline with angle 0 = 30°. Simultaneously, the small particle A moves along the slot located at distance d = 0.3 m from the center of the disk. At the instant shown, the disk has a constant clockwise angular speedw = 1 rad/s, and the particle is in position x = 0.4 m which is increasing at a constant rate į = 1.3 m/s.
