Common carrier. A common carrier in common law countries (corresponding to a public carrier in civil law systems, usually called simply a carrier) is a person or company that transports goods or people for any person or company and that is responsible for any possible loss of the goods during transport.
Best Answer: Torque is a twisting force. It is the power output of an engine at one specific point in time. The first number, 200 in your expample, is the amount of torque. In America is is measured in foot/pounds. The second number, 400 in your example, is the RPM where that torque number occurs.
Torque is the twisting force that tends to cause rotation. The point where the object rotates is known as the axis of rotation. Mathematically torque can be written as T = F * r * sin(theta) , and it has units of Newton-meters.When the sum of all torques acting on an object equals zero it is in rotational equilibrium.hile often heard as an automotive term, torque is actually a general physics term that has many applications. Torque is defined as a twisting force that tends to cause rotation. We call the point where the object rotates the axis of rotation.
