11 Examples Of Elastic Force

The elastic force examples we encounter in our life explain how the resisting force is possessed by an elastic object when it is compressed or stretched by an external force. The articles discuss such elastic force examples, which are listed below:

Resistance Band

Have you noticed that pulled resistance band would stretch but doesn’t break?

When we stretch the flexible connectors like rope, string, band, etc., by pulling, it develops the tension force on all of them. The tension force then transfers the external pull force to their ends, which can stretch our body muscles. That is why resistance bands are mostly used for stretching exercises.

But at a certain point of stretch, the connectors give resistance to the pull force. The more we pull or stretch the band, the more resistance it will provide to us. Once we release the pull on the band, the tension force gets removed, and the band gets its original shape.

The resistance force of the connectors that prevent it from breaking by resist stretch and helps the connectors to regain original form once we remove the external force is called ‘elastic force’.

Rubber Band

Due to their elastic nature, the rubber bands easily get stretched when we pull.

But have you noticed the bands could stretch up to a specific limit? That is because, at this point, the rubber bands possessed the elastic force that counterpart the external pull by resisting the further stretch or change in rubber shape. The more pull force we exert on the rubber, the more the elastic force it will exert back.

Once we removed our pull on the rubber bands, the elastic force released as the rubber returned to its initial shape.

The restoring force or elastic force is usually proportional to the amount of stretch; which Hook’s Law describes.

Elastic Waistband

Nowadays, the elastic waistband can be used while manufacturing several outfits for proper fitting.

If the person’s body size is larger than its outfit size with a waistband, it would have expanded to make a person comfortable while wearing the outfit.

But when the person removed the pull on the waistband by removing the outfit, the elastic force restores the waistband size to its original.

Spring Toys

Spring is one of the flexible connectors. That is why it also exerts the elastic force when it undergoes deformations such as expansion and compression depending on external force.

Due elastic force in the spring, it return to original shape just like the stretchy materials. Therefore, springs have importance in the entertainment division. It is extensively used in many toys like toy telephones, spring heads, etc.

Spring Mattress

Other than entertainment purposes, springs can be used in the hospitality domain and household.

When the external force gets revoked, the springs can recover their shape due to the elastic force. Therefore, many mattresses in lavish houses are manufactured using spring or memory foam in the modern world to raise the comfort level.

Guitar Strings

When we pull guitar strings, the tension force develops on the strings tied at both the guitar – cause strings to be dislocated from their original position by making them vibrate.

Since strings have a property to regain its original shape, it exerts the elastic force to counterpart the tension force.

The interaction between action and reaction force on the guitar strings produces sound energy.

Bow’s String

The elastic force also plays a vital role in archery since the bow has a flexible connector such as string.

Like the stretchy elastic material, the string has the ability to regain its shape due to elastic force.

Therefore, when the archer pulls the bow’s string along with the arrow and releases it, the string exerts the elastic force towards the pull and gets back to its original shape. The action helps the arrow to travel forward when it is released and hit as per the aim.

Sports Balls

While playing the football game, we noticed a slight compression on the football when we hit the ball. Since the football is made of elastic material, it also can regain its original shape due to elastic force.

Similarly, case you will notice when we hit the golf ball with a golf stick.

When you hit the rubber ball on the ground, we exert the external force on the ball downward. Since the rubber ball is elastic, it bounces back upward after it hit the ground due to elastic force. The more we hit the ball hard on the ground, the more height it bounces back.

Trampoline Sheet

A Trampoline, a piece of equipment that consists of a strong fabric sheet joined by springs, can be used for acrobatic or gymnastic exercises.

The fabric sheet in the trampoline is highly elastic in nature. Hence, when anyone jumps on a trampoline sheet, it exerts the push force in the downward direction.

In the reaction to the external force, the sheets and spring developed elastic force to counterpart the external force. The elastic force helps the jumpers to bounce back as the trampoline sheet and string regain their original shape.

Bungee Jumping Cord

The cord plays a prominent role in adventure activities such as bungee jumping since the it is elastic and resists extensive pulling and change in its shape.

Therefore, when a bungee jumper jumps from the height and reaches the ground surface, they won’t hit the ground abruptly. In contrast, the bungee cords elastic force helps the jumper bounce back just before reaching the ground surface to avoid any accidents.

The more the elastic cord is pulled, the more elastic force it will hold to recover to its original shape and the more bouncing motion the jumper exhibits during falling.

You may be questioned how our body exerts the elastic force?

When we consume some more amount of food, our abdomen goes stretch? But eventually, the elongated abdomen recovers its original shape once the food digest.

When we do any exercise, we stretch our body muscles, which results in a better body shape with time. 

That shows how elasticity is crucial for our body to facilitate flexibility or avoid stiffness.

How does an Elastic material exert Elastic Force?

Ans: When we stretch or compressed any elastic material by pulling, it exerts the elastic force as follows:

Stretching the elastic materials means exerting the external force on them. Newton’s third law of motion says that “every action has an equal and opposite reaction.” Therefore, to counterpart the external force, the elastic material exerts an equal force in the opposite direction. The equal and opposite force is the elastic force that helps to get rid of compression we created on elastic material to regain its original shape.

Which is more Elastic Rubber or Steel?

Ans: The rubber has more elasticity than steel as follows:

The material’s elasticity depends on the value of Young’s modulus, which defines how easily the material can bend or stretch. Young’s modulus of the material is the ratio of the strain to the stress.

When we applied the same amount of stress to both rubber and steel, it produced a larger strain on rubber compare to steel. That means the steel has a more significant value of Young’s modulus. Simply, we can say steel is harder to stretch or bend compared to steel.
