Of course, the dimensional equivalence of these units is not simply a coincidence; a torque of 1 Nm applied through a full revolution will require an energy of exactly 2" joules. 
Time and rotational distance are related by the angular speed where each revolution results in the circumference of the circle being travelled by the force that is generating the torque. On the right hand side, this is a scalar product of two vectors, giving a scalar on the left hand side of the equation.
Torque has dimensions of force times distance and the SI unit of torque is the " newton meter " (Nm).
For metric SI units power is watts, torque is newton meters and angular speed is radians per second (not rpm and not revolutions per second).
Some people (e.g. American automotive engineers) use horsepower (imperial mechanical) for power, foot-pounds (lbf"ft) for torque and rpm (revolutions per minute) for angular speed. This conversion factor is approximate because the transcendental number " appears in it; a more precise value is 5252.11312203255. It comes from 33,000 (ft"lbf.
Understanding the relationship between torque, power and engine speed is vital in automotive engineering, concerned as it is with transmitting power from the engine through the drive train to the wheels.
Torque is part of the basic specification of an engine : the power output of an engine is expressed as its torque multiplied by its rotational speed.
Steam engines and electric motors tend to produce maximum torque close to zero rpm, with the torque diminishing as rotational speed rises (due to increasing friction and other constraints). Therefore, these types of engines usually have quite different types of drivetrains from internal combustion engines.
Internal-combustion engines produce useful torque only over a limited range of rotational speeds (typically from around 1,000"6,000 rpm for a small car).
Power and Torque Explained A clear explanation of the relationship between Power and Torque, and how they relate to engine performance.
Relationship between force (F), torque ("), and momentum vectors (p and L) in a rotating system.
In physics, a torque (") is a vector that measures the tendency of a force to rotate an object about some axis (center).
If the force is perpendicular to the displacement vector r, the moment arm will be equal to the distance to the centre, and torque will be a maximum for the given force.
The rotational analogues of force, mass, and acceleration are torque, moment of inertia, and angular acceleration, respectively.
The torque caused by the two opposing forces F g and - F g causes a change in the angular momentum L in the direction of that torque. This causes the top to precess.
The construction of the "moment arm" is shown in the figure below, along with the vectors r and F mentioned above. The problem with this definition is that it does not give the direction of the torque but only the magnitude, and hence it is difficult to use in three-dimensional cases.
A force of three newtons applied two meters from the fulcrum exerts the same torque as one newton applied six meters from the fulcrum. This assumes the force is in a direction at right angles to the straight lever.
The force applied to a lever, multiplied by its distance from the lever's fulcrum, is its torque.
The magnitude of a torque is defined as force times the length of the lever arm (radius).
L is the angular momentum vector t stands for time. As can be seen from either of these relationships, torque is a vector, which points along the axis of the rotation it would tend to cause.
In the case of torque, the unit is assigned to a vector, whereas for energy, it is assigned to a scalar.
E is the energy " is torque " is the angle moved, in radians. Other non-SI units of torque include " pound-force - feet " or "foot-pounds-force" or "ounce-force- inches " or "meter- kilograms-force ".
For different units of power, torque, or angular speed, a conversion factor must be inserted into the equation.
Mathematically, the equation may be rearranged to compute torque for a given power output.
For a two-dimensional situation with horizontal and vertical forces, the sum of the forces requirement is two equations: " H 0 and " V 0, and the torque a third equation: " " 0.
For an object to be in static equilibrium, not only must the sum of the forces be zero, but also the sum of the torques (moments) about any point.
If a person places a force of 10N on a spanner which is 0.5 m long, the torque will be 5Nm, assuming that the person pulls the spanner by applying force perpendicular to the spanner.
Even though the order of "newton" and "meter" are mathematically interchangeable, the BIPM ( Bureau International des Poids et Mesures ) specifies that the order should be Nm not mN. N"m is also acceptable. The joule, which is the SI unit for energy or work, is also defined as 1 Nm, but this unit is not used for torque.
The torque peak cannot, by definition, appear at higher rpm than the power peak.
The peak of that torque curve usually occurs somewhat below the overall power peak.
"Horsepower and Torque" An article showing how power, torque, and gearing affect a vehicle's performance.
The direction of the torque can be determined by using the right hand rule : Using your right hand, curl your fingers in the direction of rotation, and stick your thumb out so it is aligned with the axis of rotation.
The varying torque output over that range can be measured with a dynamometer, and shown as a torque curve.
The concept of torque, also called moment or couple, originated with the studies of Archimedes on levers.
If torque is allowed to act through a rotational distance, it is doing work.
By the definition of torque: torqueforce x radius. We can rearrange this to determine forcetorque/radius.
Torque is also the easiest way to explain mechanical advantage in just about every simple machine.
As of version 1.5, the Torque Indie License allows the engine to be used by independent game developers for USD $150.00 per programmer, provided the programmer is not employed by a company with an annual revenue of greater than $250,000.
The Torque engine has since been available for license from GarageGames to independent and professional game developers.
Several Xbox Live Arcade games have been released using the Torque engine, most notably Marble Blast Ultra.
Torque supports networked games over LAN and the internet with a traditional client-server architecture.
Developers who believe Torque is poor often cite the documentation as one of its weaknesses. These developers believe that while a large amount of documentation exists, much of it "is simply lacking. It works, but it simply is not enough." GarageGames has made efforts to mitigate this by creating the largely community driven Torque Developer Network (or the TDN for short) to serve as a documentation for its products.
