Why is anti clockwise positive

The right-hand rule can also relate the direction of the torque to the direction of rotation. If the fingers were to curl, they would curl in the direction of rotation.

Thus, if you curl the fingers of your right hand in the direction of rotation, your thumb will point in the direction of torque. The Maxwell's right hand thumb rule states that ' When the conductor is held in your right hand , such that the direction of the thumb points the direction of the current and the curled finger gives the direction of the magnetic finger.

Typical nuts, screws, bolts, bottle caps, and jar lids are tightened moved away from the observer clockwise and loosened moved towards the observer counterclockwise in accordance with the right-hand rule.

A moment applied to the body is positive if it tries to turn the body in a counter-clockwise direction and negative if it tries to turn the body in a clockwise direction. Why anti clockwise torque is positive? Asked by: Doug Ernser. How do you know if rotation is positive or negative? Which type of moment of force is taken as positive? How do you know if its clockwise or anticlockwise? Can a moment be negative? What is the principle of moments?

What is difference work and power? Is moment a force? Is rotation clockwise positive? Does rotation change orientation?

This is the logic behind taking anticlockwise as positive and clockwise as negative. Clockwise moments: If the force has tendency to turn or rotate a body in clockwise direction, the moment of force is called clockwise moment.

Just like with screws and bottle caps, the following applies: water taps are closed turning them clockwise and opened counterclockwise. While your fan should spin counterclockwise during the summer months, it needs to spin clockwise during the winter months. Fans should also spin at a low speed so they can pull cool air upward. The gentle updraft pushes warm air, which naturally rises to the ceiling, down along the walls, and back to the floor.
