The initially stationary uniform disk of mass m₁ = 2.5 kg and radius b = 280 mm is allowed to drop onto the moving belt from a very small elevation. Determine the time t required for the disk to acquire its steady-state angular speed. The belt drive pulley rotates with a constant counterclockwise angular velocity w = 190 rad/s. The mass m₂ is 3.8 kg, the coefficient of friction UK is 0.20, and the radius r of the small pulley is 36 mm. Ignore any sag in the belt. 36 m₁ A Uk Answer: t = i m₂ (0) S
