Torque

What is static equilibrium in the context of Torque?

• Static equilibrium occurs when the sum of all torques acting on an object is zero, resulting in no rotation.

• Static equilibrium occurs when an object is in motion with constant velocity.

• Static equilibrium occurs when the net force acting on an object is maximized.

• Static equilibrium occurs when an object is at rest and experiences no external forces.

What is the difference between Torque and force?

• Force is a linear quantity that causes linear motion, while torque is a rotational quantity that causes rotational motion.

• Torque is a linear quantity that causes linear motion, while force is a rotational quantity that causes rotational motion.

• Both torque and force are linear quantities that cause linear motion.

• Torque and force are the same and can be used interchangeably.

What is the formula for calculating Torque?

• Torque (τ) = Force (F) × Distance (r) × sin(θ)

• Torque (τ) = Force (F) + Distance (r) + θ

• Torque (τ) = Force (F) / Distance (r) × θ

• Torque (τ) = Force (F) - Distance (r) × sin(θ)

What units are used to measure Torque?

• Pound-feet (lb-ft)

• Newton-meters (Nm)

• Kilogram-meters (kg-m)

• Joules (J)

What is dynamic equilibrium in the context of Torque?

• A state where an object is at rest and the net torque is zero.

• A condition where an object is moving with constant angular velocity and the net torque is zero.

• A situation where an object is accelerating and the net torque is increasing.

• A scenario where an object is rotating with varying speed and the net torque is constant.

What is the effect of increasing force on Torque?

• Increasing the applied force decreases the torque, assuming the distance from the axis of rotation remains constant.

• Increasing the applied force increases the torque, assuming the distance from the axis of rotation remains constant.

• Increasing the applied force has no effect on torque, regardless of the distance from the axis of rotation.

• Increasing the applied force only affects torque if the distance from the axis of rotation is also increased.

What is Torque?

• 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.

• A type of energy that is stored in an object due to its position.

• The speed at which an object rotates around an axis.

• The force that opposes the motion of an object.

What is the relationship between Torque and centripetal force?

• Torque is only related to linear motion.

• Centripetal force is a type of torque.

• Torque relates to rotational motion, while centripetal force is necessary for maintaining circular motion.

• Torque and centripetal force are unrelated concepts.

What is the significance of the distance in Torque calculation?

• The distance has no effect on torque calculation.

• The distance affects the amount of torque produced; a longer lever arm increases torque for the same amount of force.

• The distance only matters when calculating force, not torque.

• The distance is irrelevant in mechanical systems.

How does Torque affect the performance of a vehicle?

• It increases the vehicle's top speed.

• It affects a vehicle's acceleration and ability to perform work, such as towing or climbing hills.

• It reduces fuel consumption significantly.

• It improves the vehicle's braking system.
