Question

How do you use the right hand rule with torque?

Answer 1

To determine the sign and direction of torque using the right hand rule, curl the fingers of your right hand in the direction of the force vector. The direction your thumb points represents the direction of the torque. To calculate the net torque, add the individual torques obtained using the right hand rule.

Step-by-step explanation:

When using the right hand rule with torque, you can determine its sign and direction. The right hand rule states that if you curl the fingers of your right hand in the direction of the force vector, the direction in which your thumb points represents the direction of the torque. If the torque is positive, it will be out of the page, and if it's negative, it will be into the page.

To calculate the net torque, you need to consider individual torques about a common axis and sum them. Each torque vector can be found using the right hand rule and then added algebraically to determine the net torque.

Answer 2

Refer to the explanation.

Step-by-step explanation:

The right-hand rule is a useful tool for determining the direction of torque in rotational dynamics. To apply the right-hand rule to torque, follow these steps:

• 1. Identify the Force and the Lever Arm: First, identify the force being applied and the lever arm, which is the perpendicular distance from the axis of rotation to the line of action of the force.

• 2. Point Your Fingers: Extend your right hand and point your fingers in the direction of the lever arm.

• 3. Curl Your Fingers: Next, curl your fingers toward the direction in which the force is applied.

• 4. See Where Your Thumb Points: The direction your thumb points indicates the direction of the torque. We typically say the direction is "into the page" or "out of the page."

For example, if you apply a force in a clockwise direction, your fingers would curl in the direction of the force, and your thumb would point into the page or screen. This indicates that the torque vector is directed into the page or screen. Conversely, for a counterclockwise force, your thumb would point out of the page or screen, indicating the torque vector in that direction.

Thus, we can conclude that:

• Clockwise torques are negative
• Counterclockwise torques are positive
