# What Is An Extended Object In Static Equilibrium?

An extended object in static equilibrium is an object which is in a state of equilibrium and does not move. This state is known as static equilibrium. The object is said to be in static equilibrium when it is in a state of rest and all forces applied to it are in balance. This means that the sum of all the forces on the object is zero.

An extended object can be anything from a simple structure such as a bridge or a complex system such as a machine. Extended objects are usually composed of multiple parts or components. The components of the object can be arranged in a variety of ways. For example, a bridge might have several parts arranged in a way that provides support for the structure. Similarly, a machine might have several components arranged to perform a specific task.

## What is the Equilibrium Condition?

In order for an extended object to be in static equilibrium, the net force acting on it must be zero. This means that the sum of all the forces acting on the object must be equal to zero. The equilibrium condition can be expressed mathematically as follows:

Fnet = 0

Where Fnet is the net force acting on the extended object. In other words, for an extended object to be in static equilibrium, the net force must be equal to zero.

## Examples of Extended Objects in Static Equilibrium

A bridge is a prime example of an extended object in static equilibrium. A bridge is composed of many different parts, such as beams, columns, and trusses. These parts are arranged in a way that provides support for the bridge and keeps it in static equilibrium. As long as the net force acting on the bridge is equal to zero, the bridge will remain in static equilibrium.

Another example of an extended object in static equilibrium is a crane. A crane is composed of many different parts, such as the boom, winches, and counterweights. These parts are arranged in a way that allows the crane to lift heavy objects without tipping over. As long as the net force acting on the crane is equal to zero, the crane will remain in static equilibrium.

## How to Calculate the Net Force?

The net force acting on an extended object can be calculated by summing all the forces acting on the object. The sum of the forces is called the net force. The net force is calculated by adding up all the forces acting on the object and then subtracting any opposing forces.

For example, if a bridge has four columns, each with a force of 10N, then the net force acting on the bridge is 40N. In order for the bridge to remain in static equilibrium, the net force must be equal to zero. This means that any opposing forces on the bridge must be equal to 40N.

## Conclusion

An extended object is in static equilibrium if the net force acting on it is equal to zero. This means that the sum of all the forces acting on the object must be equal to zero. Examples of extended objects in static equilibrium include bridges and cranes. The net force acting on an extended object can be calculated by summing all the forces acting on the object. This net force must be equal to zero in order for the extended object to remain in static equilibrium.
