The direction is perpendicular to both the radius from the axis and to the force. It is conventional to choose it in the right hand rule direction along the axis of rotation. The torque is in the direction of the angular velocity which would be produced by it in the absence of other influences.
Describe how the magnitude of a torque depends on the magnitude of the lever arm and the angle the force vector makes with the lever arm. Determine the sign (positive or negative) of a torque using the right-hand rule. Calculate individual torques about a common axis and sum them to find the net torque.
17 Οκτ 2024 · To determine the sense of rotation that such a torque vector would correspond to, about the axis defined by the torque vector itself, we use The Right Hand Rule For Something Curly Something Straight.
The third way to calculate torque, as was alluded to in Section 1.6 is to use the right hand rule to identify the axis of rotation. The first way (the scalar method) uses | M | = | r | | F | sin Θ, and often the angle between the position vector and force is 90 degrees.
In mathematics and physics, the right-hand rule is a convention and a mnemonic, utilized to define the orientation of axes in three-dimensional space and to determine the direction of the cross product of two vectors, as well as to establish the direction of the force on a current-carrying conductor in a magnetic field.

21 Μαΐ 2023 · If we perform a cross-product of the position vector (up to the right) and the force vector (up to the left), the right-hand-rule results in a vector that also points out of the page. We therefore write: \[ \overrightarrow \tau = \overrightarrow r \times \overrightarrow F \]
