Rubber Band Equation

W elastic potential energy in joules.

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 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. Obtain a rubber band at least 0 5 cm wide. Substitute the slope you found in step 6 and one of your two points into the equation y sx i and solve for i.

However there is no. 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. First stretch a rubber band and hold it in position for a few seconds. Figure 5 large band tension equations for each band.

When a rubber band is stretched some of the network chains are forced to become straight. Viewed 4k times 3. Individual 4 carbon backbone units are forced into rotational conformations that have longer end to end distances and this restricts the number of conformations states that are thermally accessible. 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.

You will feel a slight warming effect. Use your equation to determine how many rubber bands would be needed to drop barbie from your ceiling to your floor. Polymers are essentially long chainlike molecules composed of many identical or nearly identical subunits. The y variable is the amount of pressure necessary to stretch the band.

Elastic potential energy force x distance of displacement. Elastic potential energy is equal to the force times the distance of movement. Then write the equation for your line. Active 5 years 10 months ago.

Quickly stretch the rubber band and then press it against your lips. Equation of state of a rubber band. I have non zero tension at equilibrium. The x variable is the number of inches the band is stretched to.

Elastic potential energy is the stored energy of a compressible or stretchable object like a spring or rubber band or molecule. 3 begingroup i have the following question that i attached in png format. You will need to measure this distance in cm. A rubber band is a single molecule as is a latex glove.

You can also carry out the reverse process. Then quickly release the tension and press the rubber.
