Torque & Equilibrium definitions Flashcards

A state where net force and net torque on an object are zero, resulting in no acceleration or rotational motion.

Occurs when the sum of all forces on an object is zero, leading to no linear acceleration.

Achieved when the sum of all torques on an object is zero, preventing angular acceleration.

A condition where both linear and rotational equilibrium are present, with no linear or angular velocity.

A measure of the force causing an object to rotate, calculated as force times distance times sine of the angle.

The line around which an object rotates, crucial in determining the effect of torques.

The point in an object where its mass is evenly distributed and where weight force acts.

The pivot point around which a lever or bar rotates, often providing a normal force.

The force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

The vector sum of all forces acting on an object, determining its linear acceleration.

The sum of all torques acting on an object, determining its angular acceleration.

The rate of change of an object's angular position, zero in static equilibrium.

An object with a fixed shape that does not deform under force, often used in equilibrium analysis.

A positive torque direction, typically opposing clockwise torque in equilibrium scenarios.

A negative torque direction, often balanced by counterclockwise torque in equilibrium.
