What is principles of moment?In physics, the term "moment" can refer to many different concepts:
Moment of force is a synonym for torque, an important basic concept in physics, civil engineering, and mechanical engineering.In the context of mechanical engineering, the terms are not necessarily interchangeable, but one or the other may be preferred in a specific context. For example, "torque" is usually used to describe a rotational force down a shaft, for example a turning screw-driver, whereas "moment" is more often used to describe a bending force on a beam.
Moment arm is a quantity used when calculating torque. The Principle of moments is a theorem concerning torques.*torque=The measure of the force applied to an object to produce rotational motion, usually measured in foot-pounds. Torque is determined by multiplying the applied force by the distance from the pivot point to the point where the force is applied.
