A cylinder on John Lennon Guttenbergs printing press has a 3

A cylinder on John Lennon Guttenberg\'s printing press has a 32.8 cm diameter. The linear speed of a point on the cylinder\'s surface is 133 meters per minute. What is the angular speed of the cylinder in revolutions per hour?

Solution

v = r w

w = 133 / (16.4 * 10^-2) = 810.96

810.96 * [1 rev / 2 pi rad] * [60 min / 1 hr]

= 7744 rev/hr
