Two equal, but oppositely directed forces acting simultaneously on opposite sides of an axis of rotation. Since the translatory forces (forces that produce linear motion) cancel out each other, a force couple produces torque (rotatory forces) only. The magnitude of the force couple is the sum of the products of each force and its moment arm.

Which motion does a couple produce?

It has a resultant moment but does not have resultant force.


What conditions must exist in order for a force to do work on an object?

The force must couple to the object. The point of application of the force must be able to move in the direction of the force.

How do you apply a force so that an object will spin?

apply two forces , known as a couple


Give an example of a case when the resultant force is zero but resultant torque is not zero?

A couple.


What is the difference between torque and couple?

The turning effect of a force is called torque or moment of the force. SI unit of torque is Newton-Metre. T = FL i.e Torque = Force x Moment arm A couple is formed by two unlike parallel forces of the same magnitude but not along the same line.


What is a couple according to physics?

A couple is two forces equal and opposite to each other and separated by a distance. The magnitude of the force times the distance is called a moment


What is the definition of couple stress fluid?

When we mix additives in the oil/fluid, the forces which are present in the fluid opposes the forces of additives. This opposition makes a couple force and hence a couple stress is induced in the fluid. This type of fluid is known as couple stress fluid.

What keeps a ship level?

When a vessel is floating upright, there are two forces acting on it. The buoyancy force acts upwards and the gravity force acts donwards, cancelling each other. If a heeling force acts upon it (such as a wave hitting it), these forces are upset, and then a couple is formed. If the ship is loaded properly, a righting couple results, bringing the ship upright. If the center of gravity is too low, then an upsetting couple will result, capsizing (overturning) the ship.


What is Bjerknes force?

Bjernkes force is exerted on a gas bubble when the gas bubble is in a liquid, is subjected to an acoustic pressure field, and undergoes volume pulsations. If the acoustic pressure gradient is not zero, it can couple with the bubble oscillation to produce a translational force on the bubble. This force is known as the primary Bjerknes force.


Is a fixing moment a couple?

A moment, M, is a rotational force measured in inch pounds; a couple is two forces, P, acting in opposite directions and separated by a distance, d. The product Pd is the couple and is measured in inch -pounds, and is an equivalent moment.
