A viscometer is an instrument for measuring the viscosity of a fluid. In a simple form, it consists of two concentric cylinders, with the outer cylinder fixed and the inner cylinder free to rotate. The space between the two cylinders is filled with the fluid in question, and the torque required to rotate the inner cylinder at a constant speed is measured. One such device consists of two 21.0-cm long cylinders, one 15 cm in diameter and the other 15.4...

To maintain their bone density and other signs of a healthy body while on a long space trip, the inhabitants of a cylindrically-shaped living space want to generate a 1-g environment while moving through space. Assume the cylinder has a diameter of 250 m, they live on the inner surface farthest from the center, and the space ship is initially not rotating about its central axis. For minimal disruption, the maximum (constant) angular acceleration allowed is 0.00010 rad/s2. How long...

Assuming that a day is exactly 24 hours long (and neglecting the motion of the Earth around the Sun, which adds a small correctionto this): (a) What is the angular velocity of an object resting on the surface of the Earth, as seen from a true inertial (non-spinning) frame? (Give your answer in rad/s. You’ll want to use scientific notation here.) (b) The radius of the Earth is approximately 6.37×106m. What is the centripetal acceleration of an object rest-ing on...

A long string is wrapped around a 6.5-cm-diameter cylinder, initially at rest, that is free to rotate on an axle. The string is then pulled with a constant acceleration of 1.5 m/s^2 until 1.1 m of string has been unwound. If the string unwinds without slipping, what is the cylinder's angular speed, in rpm, at this time? Express your answer to two significant figures and include the appropriate units.
