RotaryCraft is heavily based on real world physics from its power system, to its machines, to the properties of the materials used to craft those machines, everything is designed around or adapted to the physics of everyday life. A deep understanding of these physics is not necessary to have fun with RotaryCraft, however a cursory understanding will help in grasping the concepts behind the mod and provide a fun enjoyable experience. RotaryCraft is not just a modification to the game Minecraft intended for enjoyment, it is an opportunity for it's users to learn about physics and apply what they have learned in ways mimicing real world situations.

"In physics, power (symbol: P) is defined as the amount of energy consumed per unit time. In the MKS system, the unit of power is the joule per second (J/s), known as the watt (in honor of James Watt, an eighteenth-century developer of the steam engine).[1] For example, the rate at which a light bulb converts electrical energy into heat and light is measured in watts—the more wattage, the more power, or equivalently the more electrical energy is used per unit time."[1][2]

Energy transfer can be used to do work, so power is also the rate at which this work is performed. The same amount of work is done when carrying a load up a flight of stairs whether the person carrying it walks or runs, but more power is expended during the running because the work is done in a shorter amount of time. The output power of an electric motor is the product of the torque the motor generates and the angular velocity of its output shaft. The power expended to move a vehicle is the product of the traction force of the wheels and the velocity of the vehicle.

The integral of power over time defines the work done. Because this integral depends on the trajectory of the point of application of the force and torque, this calculation of work is said to be path dependent."[2]

Rotarycraft Handbook DescriptionEdit

"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. Angular 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."

FormulasEdit

Power of a Body in Angular Motion

   P = τω
   where
   P = power (W)
   τ = torque or moment (Nm)
   ω = angular velocity (rad/s)
