The right hand rule is a method used to determine the direction of torque in a rotational system. It states that if you point your right thumb in the direction of the applied force, with your fingers curled in the direction of rotation, then your fingers will point in the direction of the torque.
The right hand rule is used because it follows the convention of positive rotation in a counterclockwise direction and negative rotation in a clockwise direction. This convention is widely used in physics and engineering.
In a real-world scenario, you would place your hand on the object that is rotating and point your fingers in the direction of rotation. Then, you would apply a force with your thumb in the direction of the applied force. The direction your fingers point in is the direction of the torque.
Yes, the right hand rule can be used in any rotational system as long as the direction of rotation and applied force are known. It is a universal method for determining torque direction.
Yes, there is also a left hand rule for determining torque direction. It follows the same concept, but with the left hand instead of the right hand. Additionally, some sources may use different hand positions, such as pointing the fingers in the direction of the applied force and curling them in the direction of rotation.
