RotaryCraft

RotaryCraft adds engines, gears, shafts, coils and many machines. Machines can be used for mining, refining ores, and automatic farms.

Unlike many other mods, this mod does not use cables to transfer power and instead uses shafts to transmit power. Engines output at different torques (newton meter) and speeds (radians/second) and may require gearboxes to get the correct torque or speed to power certain machines. Shaft power can also be converted into BuildCraft MJ, Thermal Expansion RF and Universal Electricity. Many of the machines require different speeds and torques than what the different engines output. Sometimes a gearbox is required, or just another engine.

Realism is at the core of this mod, and figuring out what is needed to run each machine requires math.
