# Static Force: 17 Examples You Should Know

Have you ever wondered why we can remain stationary for a specific time it is because of static force. This force acts on an object at rest. Let us know more examples of static force in this article.

## Bicycle resting on the bridge.

A bicycle resting on a bridge is an example of static force.

A bicycle that rests on a bridge exerts both force and pressure on the surface of contact. This force does not vary any change in position or state of the bicycle. The type of force between a bicycle and the bridge is static force.

## Key hung on a Keyholder.

A key hung on a keyholder is an example of static force. The key is pulled downwards by the gravitational pull of the earth. But the push and reaction force exerted by the key holder and the hook makes the key remain in the same position. Thus, static force helps the key to remain stationary.

## Hook attached to a loop ring.

The hook attached to a loop ring does not get displaced from its original position. The push and reaction force acting between the surfaces in contact restricts the loop ring from changing its state and position. The force which maintains the stationary position of the ring is static.

## Paint frame on a Wall.

When we hang a painted frame on a wall, static force keeps it in a fixed position. The frame is pulled in a downward direction by the gravitational force of the earth. Simultaneously, the push and reaction force of frame and wall gets cancelled and becomes balanced and keeps it stationary.

## Boat sailing on the surface of the water.

Boat sailing on water surface experience a static force which helps it to remain stationary for some time. The boat is pulled downward by its weight, but the buoyant force between water and boat surfaces tends to move it upwards. Thus, both the opposite forces cancel and act as static forces.

## Body placed at a certain height.

The body placed at a certain height remains in the same position due to static force. When we place it at some height, a certain amount of potential energy gets store in it. The forces acting on the body cancel each other, becomes a static force and helps it to be in a stationary position.

## An individual who stands on the ground experiences static force.

When an individual stands on the ground, he experiences a static force. In this case, the gravitational force and normal force act opposite, cancel each other and become a static force. However, it makes him stay stationary and can be changed into dynamic force when he walks.

## Pushing a brick wall.

When you try to push a brick wall or any wall, it does not move. Even if you apply a large amount of force, it remains fixed and rigid. It is because forces act in the opposite direction on the wall’s structure and restrict the change in position of the wall.

Carrying a load overhead is an example of static force. The force required to keep the load and the gravitational force acts opposite and helps a person hold the load over his head in the same position. It is because of static force.

## Strings attached to the bow.

Strings attached to the bow remain in the same position due to static force. The opposite forces act between the string and endpoints of the bow, which restricts the change in string position. The force which acts here becomes balance and act as a static force, and hence is an example of static force.

## A Clock hung on a nail.

A clock hung on a nail remains there due to static force. The clock is pulled downward by gravitational force, but the normal forces tend to move it upward. These forces act between surfaces of the clock and nail, which restricts its movement and makes it remain fixed due to static force.

## Moving a Heavy object.

We require a certain amount of energy to move a heavy object and is an example of static force. While moving it, we can feel friction. The friction force has a large magnitude and acts in a direction opposite to the force applied. Therefore, the force applied is less and does not change the position of the object.

## Straw inserted in soft drinks.

We usually drink juice with the help of a straw; here, the straw remains there due to static force. The push and pull forces act simultaneously between the surface of the straw, cup and soft drink, which cancels gradually and becomes a static force and makes the straw remain in the same position.

## Montgolfier balloons.

A Hot air/ Montgolfier balloon is an example of static force which occurs in the air. It reaches a certain height when released from the ground. Many forces simultaneously act in the opposite direction, cancel, and become a static force, making it remain stationary in the air.

## Fan attached to the ceiling.

Fan, when switched off, remains in a stationary position due to static force. Gravitational force tends to pull the fan downwards, but both push and reaction forces simultaneously act on it and cancel each other. Thus, the forces become balanced; in this case, the balanced force is called static force.

## Storage tank.

The water storage tank remains at a certain height with the help of static force. When a water tank gets placed on a stand, gravitational force attracts it downwards, but normal force moves it upwards. These opposing forces cancel and act as a static force, making the tank remain fixed.

## Airplane on the runway.

We usually find an airplane parked on a runway; the giant airplane requires static force to remain in that fixed position. Here gravitational force tends to pull it downwards, but as usual, the normal force comes into play, and these opposing forces cancel each other and become static and restrict the motion.

## Chessboard.

The chess coins stay on the chessboard with the help of static force. The action and reaction forces that act simultaneously between coins and the board gradually decrease and become a static force, which then helps the coins to remain fixed unless it moves.

## What force is static?

Static force is the force that occurs on an object when it is not moving.

If you move an object at rest, it does not move because it is restricted by a static force which comes into play when opposite forces cancel each other.

## Is static force equal to net force?

In static equilibrium, all the forces balance each other.

The object is either not moving or moving with uniform velocity, and hence net force is zero.

## What does static force depend on?

The static force depends on the two surfaces, which are relatively stationary to each other.

In static force, the value of force is the value that it requires to prevent the object’s motion.

## Is static force a contact force?

Static force is contact and balanced force.

If any two surfaces are not in contact, they cannot exert force on each other, and static force is the type of force that restricts objects from moving further.

## Is static force a self-adjusting force?

Static force is a self-adjusting force.

The static force keeps an object at rest and can adjust the force according to the applied force.
