The disk rotates about a fixed axis through point o with a clockwise angular velocity wo = 20 rad/s and a counterclockwise angular acceleration 0o = 4.1 rad/s2 at the instant under consideration. The value of r is 260 mm. Pin A is fixed to the disk but slides freely within the slotted member BC. Determine the velocity and acceleration of A relative to slotted member BC and the angular velocity and angular acceleration of BC. The relative velocity and...

down A hollow cylinder with inner radius R = 4.45 m rotates with constant angular velocity w around a vertical axis through its center. A small box of mass m = 4.37 kg is placed on the vertical inner surface of the cylinder and rotates with it. The coefficient of static friction between the box and the inner surface is p = 0.272, and the frictional force f between the box and the inner surface keeps the box from sliding...
