Chapter D3, Problem D3/067 The small object is placed on the inner surface of the conical dish at the radius shown. If the coefficient of static friction between the object and the conical surface is 0.17, for what range of angular velocities w about the vertical axis will the block remain on the dish without slipping? Assume that speed changes are made slowly so that any angular acceleration may be neglected. +0.40 m - m TITEL 22 Answer: 0 rad/s)...

7. A puck is placed in the inner surface of a sphere of radius R = 2.75 m. Find the angular speed of the sphere spinning with respect to its vertical axis for the puck to remain at rest a distance h=1.65 m below the sphere's center. The coefficient of static friction between the puck and the surface of the sphere is .5.

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...
