Moment micrometer

Technical Field

The utility model relates to a moment test technical field especially relates to a moment micrometer.

Background

The moment represents the physical quantity of the rotational effect produced when a force acts on an object. The product of the force and the moment arm is the moment. The moment is a vector. The magnitude of the moment of force at a point is the length of the perpendicular drawn from the point to the line of action of the force (i.e., the moment arm) multiplied by the magnitude of the force, and the direction is determined by the right-handed helix rule, perpendicular to the plane formed by the perpendicular and the force. The force to a certain axis moment is equal to the projection of the force to the moment of any point on the axis. In the international system of units, the unit of moment is newton-meters. The unit commonly used is also kilogram force, meter and the like. The moment can make the object obtain angular acceleration and change the momentum moment of the object, and the larger the moment is for the same object, the easier the rotation state is to change.
