The Right Hand Rule for Torque

The video tutorial introduces the concept of torque direction and explains how to use the right-hand rule to determine it. Through various examples, the instructor demonstrates the application of the right-hand rule, highlighting the positive and negative directions of torque. The video also discusses the relationship between torque and angular displacement, and addresses scenarios where torque is zero. The tutorial concludes with a caution against using the right-hand rule for force direction.

What is the first step in applying the right-hand rule for torque?

• Start with your left hand at the axis of rotation.

• Don't be too cool for the right-hand rule.

• Point your fingers in the direction of the force.

• Stick out your thumb in the direction of the force.

In the right-hand rule, what does the thumb indicate?

• The axis of rotation.

• The magnitude of the force.

• The direction of the torque.

• The direction of the force.

What is considered positive torque in the right-hand rule?

• Perpendicular to the board.

• Into the board.

• Out of the board.

• Parallel to the board.

How is the direction of torque determined when the force is applied in the opposite direction?

• It remains the same as the previous example.

• It is not affected by the force direction.

• It becomes zero.

• It changes to the opposite direction.

How does the right-hand rule relate to angular displacement?

• They are unrelated.

• They are opposite.

• They are in the same direction.

• They are perpendicular.

What happens to the torque when the angle between the position vector and force is zero?

• The torque is maximum.

• The torque is undefined.

• The torque is zero.

• The torque is negative.

Why is the right-hand rule not suitable for determining the direction of forces?

• It only applies to angular velocity.

• It is specifically for torque direction.

• It is only for linear forces.

• It requires both hands.
