# How do you calculate the stretch of a rubber band?

## How do you calculate the stretch of a rubber band?

To describe the stretching action of rubber bands, and explore the connection between Hooke’s Law and Young’s modulus. A simple way to understand this formula is Y=stressstrain. The stress is the amount of force applied to the object, per unit area (F/A).

Which rubber band stretches longest?

Longest rubber band chain – world record set by Allison Coach. Chesterfield Township, MI, USA — Allison Coach, 11, showed off 22,140 rubber bands stretching 6,956.68 feet long, or 1.3 miles at her school, L’Anse Creuse Middle School East – setting the new world record for the Longest rubber band chain.

### What is the K value of a rubber band?

45.0N/m
Spring constant of the rubber band is k=45.0N/m.

What is the Young’s modulus of rubber band?

1.75 mPa
Plotting stress (F/A) vs strain (∆L/L0) and fitting the points to a line gave a value for Young’s modulus of E=1.75 mPa for the rubber band shown above.

## Does a rubber band stretch when weight is applied?

If you get hold of a rubber band and pull it you are using a force on it. That force makes the rubber band get longer – it stretches. The greater the pull the longer it gets. In other words a bigger force makes the rubber band stretch more.

What happen when you stretch the rubber band and release it?

A rubber band is an elastic material in nature. When stretched, it changes its shape and when the applied force is removed, it regains its original shape. That is why a rubber band changes its shape even though it is a solid. Also, if excessive force is applied then the rubber band would break.

### What is the longest rubber band ever made?

The Guinness World Records confirmed the 12,529.4m (41,106 ft) loom band bracelet is the longest in the world.

How long was the longest rubber band chain?

19 miles
The world’s longest rubber band chain was assembled by school children from Gettysburg Elementary School in Clovis, California, USA and measured 30.5 km (19 miles) long.

## How much more weight can the rubber band take without breaking?

The rubber piece will stretch, but not break. The tension throughout the entire band, both thin and thick areas will be 1 kg of force (or to be more scientifically correct — 9.8nt of force). The tension must be constant because every part of the rubber is lifting the same 1 kg weight.

What is bulk modulus elasticity?

Bulk modulus of elasticity is simply the ratio of the pressure to the corresponding volumetric strain (or relative decrease in the volume of the substance).

### What Poisson’s ratio tells us?

Poisson’s ratio, put very simply, is the measure of how much the width or diameter of a material will change whenever it is pulled lengthwise. Or, in more technical terms, it is the measure of the change in lateral (transverse) strain over the change in linear (axial) strain.

What happens when a rubber band is stretched?

## How many photos are there of stretched rubber bands?

11,536 stretched rubber band stock photos, vectors, and illustrations are available royalty-free.

What causes a rubber band to stretch less?

The strain is the change in the length of the solid. Therefore, a solid with a greater value of Y will stretch less than a solid with a smaller Y, when the same force is applied. Rubber bands are elastic solids; they are interesting because they are thought to follow a simplified version of Young’s modulus.

### How many quarters do you need for a rubber band?

(The exact number of quarters you need will depend on the size and strength of your rubber band. You want the rubber band to visibly stretch out when you hang the quarters from it but not so much that it hits the bottom of the bottle. A strong rubber band may require more quarters, a weaker rubber band may require fewer.)

What’s the best way to make a rubber band?

Loop your small rubber band around the pencil. Continue pushing the pencil through the hole on the other side of the bottle. Tape together a stack of about 20 quarters, with a paper clip as a “hook” that you can use to hang them from the rubber band.
