What is the effect of increasing the lever arm on torque, assuming force remains constant?
Increases the torque.
What is the effect of applying a force directly through the axis of rotation?
Produces zero torque.
What is the effect of increasing the angle between the force vector and the position vector on the magnitude of the torque (up to 90 degrees)?
Increases the magnitude of the torque.
Cause: A net torque is applied to an object. Effect?
The object experiences angular acceleration.
Cause: A force is applied perpendicular to a wrench handle. Effect?
The wrench rotates, applying torque to the bolt.
What is torque?
The rotational equivalent of force; a measure of how much a force causes an object to rotate.
Define lever arm.
The perpendicular distance from the axis of rotation to the line of action of the force.
What is the relationship between torque and lever arm?
A longer lever arm results in more torque for the same applied force.
What is the formula for the magnitude of torque?
, where r is the distance from the axis of rotation, F is the force, and θ is the angle between the force and position vector.
What condition maximizes torque?
Torque is maximized when the force is applied at a 90° angle to the lever arm.
What is the difference between force and torque?
Force: A linear push or pull. | Torque: A rotational force that causes objects to spin.
What is the difference between the lever arm and the distance from the axis of rotation to the point of force application?
Lever arm: The perpendicular distance. | Distance: The direct distance, which may not be perpendicular and thus not used directly in torque calculation.
