Question

a thin cylinderical shell of inner radius 1.5 m rotates horizontally about a vertical axis at an angular speed omega . A wooden blocks rests against the inner surface and rotates with it . if the coefficient of static friction between the block and surface is 0.3 how fast must the she'll be rotating if the block is not to slip and fall​

Answer 1

Explanation:

disc of radius 4m is rotating about its fixed centre with a constant angular velocity ω=2rad/s ( in the horizontal plane). A block is also rotating ...

rmax=1m Explanation: We have a disk of radius R=4m. The disk rotates at a constant angular velocity of ω=2rads. The coefficient of friction between ... More
