Spring Constant Of A Rubber Band

After each launch have your helper.

Spring constant of a rubber band. Spring constant tells you how much a spring elongates for a given weight applied within its limit. Then using the scatter plot and a line of best fit students will determine the spring constant of the rubber band. Rick michalka over 5 years ago this project is locked. Do it for different weights.

Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and. After you get the rubber band stretched just a little bit it is very spring like. 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.

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. If i assume that i could also rotate this one. For my experimental setup i hung a rubber band from a support with a container tied to the bottom of the band. Shoot at least five rubber bands for each stretch length.

This can be repeated many times with no apparent degradation to the rubber. Description students will use isense software to record the displacement of a rubber band as weight is added. A rubber band has a spring constant of 45 n m. Plot graph pf elongation versus weight.

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. Hooke s law and elastic potential. 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. Rubber band spring constant.

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. Apply some small force on rubber band and note its elongation. When the rubber band is pulled by a force of 9 8 n how far will it stretch and what is its potential energy. Shoot more rubber bands in the same way except stretch them back to 15 cm 20 cm 25 cm or 30 cm.

Rubber elasticity refers to a property of crosslinked rubber. The variables of the equation are.
