The right hand rule for the direction of torque is described and demonstrated six times.

When choosing three vectors that must be at right angles to each other, there .

When using the Right-Hand Rules, it is important to remember that the rules assume charges move in a conventional current (the hypthetical flow of positive charges). If you applied the right hand rule correctly, it should be pointing out of the screen and indicate a positive torque, or the force that will cause the wrench to rotate counterclockwise.

Strictly speaking, torque is a vector and will have a magnitude and direction but not really a sign. (4 points) axis F ddd ; Question: 5. The torque causing the downward rotation (fall) changes angular momentum of gyroscope.

The outward torque is also called positive torque and inward torque is called negative torque. Let us say that a positive torque would make a stationary object rotate counter clockwise and a negative torque would make it rotate clockwise. We see the application of torque in many ways in our world. In order to apply either Right-Hand Rule to a moving negative charge, the velocity (v) of that charge must be reversed--to represent the analogous conventional current. If is along the negative z-axis, this produces a negative torque. In this case, the sign is simply a result of whatever direction we decide to define as positive and .

If u move ur fingers in anti clockwise direction the thumb points upwards indicating positive direction. Practice with the right-hand rule.
