Rubber Band Equation

I have done part a but i am having difficulties in part b when i proceed according to the book.

Rubber band equation. When a rubber band is stretched some of the network chains are forced to become straight. Then write the equation for your line. Quickly stretch the rubber band and then press it against your lips. Elastic potential energy is equal to the force times the distance of movement.

W elastic potential energy in joules. Ask question asked 6 years 11 months ago. You can also carry out the reverse process. Substitute the slope you found in step 6 and one of your two points into the equation y sx i and solve for i.

Polymers are essentially long chainlike molecules composed of many identical or nearly identical subunits. The x variable is the number of inches the band is stretched to. The y variable is the amount of pressure necessary to stretch the band. Equation of state of a rubber band.

You will feel a slight warming effect. Viewed 4k times 3. Elastic potential energy is the stored energy of a compressible or stretchable object like a spring or rubber band or molecule. Use your equation to determine how many rubber bands would be needed to drop barbie from your ceiling to your floor.

First stretch a rubber band and hold it in position for a few seconds. Using these equations you can calculate the velocity of the rubber band right when it is released and find that the velocity has a linear relationship with the stretch length. Obtain a rubber band at least 0 5 cm wide. Then quickly release the tension and press the rubber.

The modern rubber band is made out of natural rubber a polymer derived from the latex of a rubber tree synthetic rubber is generally not as stretchy.

Rubber band as a function of temperature and extension using a space heater to change the temperature of the rubber band 6 their experiment is used to teach data analysis methods by using multiple approaches to extract the parameters in an equation of state for the rubber band. Elastic potential energy force x distance of displacement. Figure 5 large band tension equations for each band. However there is no.

A rubber band is a single molecule as is a latex glove. I have non zero tension at equilibrium.
