# Why is the moment of couple independent of the axis of rotation even if the axis is fixed?

## Why is the moment of couple independent of the axis of rotation even if the axis is fixed?

It is independent of the axis because it work with the average of the distance and works along line of center of mass of the body.

### What is the relationship between the moment of the couple and the perpendicular distance between the force couple?

The moment of a force is equal to the magnitude of the force multiplied by it’s perpendicular distance from the point about which a moment is being taken.

#### Which of the following is correct the couple moment depends on the axis of rotation?

The couple moment depends on the axis of rotation. The couple moment depends directly on the radius vector of forces. The couple moment depends only on the distance vector between the forces. The couple moment’s direction is given by the left hand rule.

What is the moment of a force that goes through the axis of rotation?

torque, also called moment of a force, in physics, the tendency of a force to rotate the body to which it is applied.

What is couple and moment of couple?

Couple is a pair of equal and opposite forces with different line of action. Moment of Couple is the rotational effect produced by a couple. It is a vector quantity. Its unit and dimension are same as that of.

## What is meant by a couple and couple moment?

A special case of moments is a couple. A couple consists of two parallel forces that are equal in magnitude, opposite in sense and do not share a line of action. If both hands applied a force in the same direction, the sum of the moments created by each force would equal zero and the wheel would not rotate.

### What is moment of couple and expression for it?

The moment of a couple is equal to the product of either force and the perpendicular distance between the line of action of both the forces.

#### What is moment of couple?

: the product of either of the forces of a couple by the perpendicular distance between them.

Which of the following is correct for the moment of couple M caused by?

Which of the following is correct for the moment of couple M caused by two forces of same magnitude F and are separated by a distance of r? Explanation: The answer is M = rxF. The moment id the cross product of the distance and the forces. It is the direction as directed by the curling of the hand.

When determining the moment of a force about a specified axis the axis must be?

Question: Moment of a Force About a Specified Axis Learning Goal: To be able to calculate the moment of a force about a specified axis. When the moment of a force is computed about a point, the moment and its axis are always perpendicular to the plane that contains the force and the moment arm.

## How is the moment of a force about a coordinate axis determined?

To find the moment of a force about a specific axis, we find the moment that the force exerts about some point on that axis and then we find the component of the moment vector that lines up with the axis we are interested in.

### How do you determine the direction of a couple moment?

The direction of your thumb toward the thumbnail is the direction of the moment, and the curl of your fingers will determine clockwise versus counterclockwise.
