Spring Constant Of A Rubber Band

Do it for different weights. Rubber bands apparatus selection of rubber bands including broken ones hung from retort stand weights with hangers a ruler action the students hang weights from the rubber bands to determine the spring constant of the rubber bands and how linear the stress strain relationship for the bands is. I measured the initial length of the rubber band 0 200 m then added 1 coin into the bag which caused a stretch in the elastic.

Why Doesn T A Rubber Band Follow Hooke S Law Quora

F which represents force k which is called the spring constant and measures how stiff and strong the spring is and x is the distance the spring is stretched or compressed away from its equilibrium or rest position.

Spring constant of a rubber band.

Slope of this line is the spring constant. Shoot more rubber bands in the same way except stretch them back to 15 cm 20 cm 25 cm or 30 cm. Spring constant tells you how much a spring elongates for a given weight applied within its limit. If i assume that i could also rotate this one.

Rubber elasticity refers to a property of crosslinked rubber. In this case the linear function fitting the straight part of the data gives a spring constant of 17 38 n m. The minus sign shows that this force is in the opposite direction of the force that s stretching or compressing the spring. The variables of the equation are.

After each launch have your helper. Rubber band spring constant. This can be repeated many times with no apparent degradation to the rubber. Apply some small force on rubber band and note its elongation.

Then using the scatter plot and a line of best fit students will determine the spring constant of the rubber band. They can estimate the young s. Hooke s law and elastic potential. After you get the rubber band stretched just a little bit it is very spring like.

Shoot at least five rubber bands for each stretch length. The rotational spring constant for this thicker band is not surprisingly higher than the normal sized rubber band with a value of 4 92 x 10 4 n m. When the rubber band is pulled by a force of 9 8 n how far will it stretch and what is its potential energy. A rubber band has a spring constant of 45 n m.

Plot graph pf elongation versus weight. For my experimental setup i hung a rubber band from a support with a container tied to the bottom of the band. Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and. Description students will use isense software to record the displacement of a rubber band as weight is added.

It can be stretched by up to a factor of 10 from its original length and when released returns very nearly to its original length. Rick michalka over 5 years ago this project is locked.
