Torque

A projected space station consists of a circular tube that is set rotating about its center (like a tubular bicycle inner tube) . The circular formed by the tube has a inner diameter of 1.5 km and an outer diameter of 1.6 km. Where will the people inhabit this space station ? What must the rotation speed be if an effect to Earth’s gravity at the surface is to be felt by its occupants ? What torque must be applied to the space if it is to attain this speed from rest in two hours and the mass of the rotation is 187,016 kg ?
