FLASHCARD QUESTION
Front
What is torque?
Back
Torque is a measure of the rotational force applied to an object, calculated as the product of the force and the distance from the axis of rotation (lever arm).
2.
FLASHCARD QUESTION
Front
How is torque calculated?
Back
Torque (τ) is calculated using the formula τ = F × r × sin(θ), where F is the force applied, r is the distance from the axis of rotation, and θ is the angle between the force vector and the lever arm.

FLASHCARD QUESTION
Front
What units are used to measure torque?
Back
Torque is measured in Newton-meters (Nm) in the SI system.
4.
FLASHCARD QUESTION
Front
What is the relationship between force and torque?
Back
Torque is directly proportional to the force applied; increasing the force increases the torque, provided the distance from the axis of rotation remains constant.
5.
FLASHCARD QUESTION
Front
What is a lever arm in the context of torque?
Back
The lever arm is the perpendicular distance from the axis of rotation to the line of action of the force.
6.
FLASHCARD QUESTION
Front
What happens to torque if the angle of force application is 90 degrees?
Back
If the angle of force application is 90 degrees, the torque is maximized because sin(90°) = 1, making the torque equal to the product of the force and the lever arm.

FLASHCARD QUESTION
Front
What is the effect of increasing the distance from the axis of rotation on torque?
Back
Increasing the distance from the axis of rotation (lever arm) increases the torque for a given force.
