W/kW/MW - Watts/Kilowatts/Megawatts - a unit of power (energy per unit time). 1W = 1 Joule per second.\n\nNm - Newton-meters - a unit of torque (force times distance).\n\nrad/s - Radians per second. A unit of angular (rotational) velocity. 1 rad/s = 9.55 rpm.\n\nRadian - A unit of angle, equal to 180/pi (57.3) degrees; there are 6.28 radians in a full circle.

Torque is the 'strength' of a turn; greater torques can exert greater loads. Therefore, a machine that requires more force to operate, such as the Compactor, will naturally require more torque than one like the Woodcutter.\n\nAngular velocity is the rotational speed. For example, a machine that mixes things quickly, such as the Fractionator, will require a greater angular velocity than one which mixes them more slowly, like the Fermenter.
