Rubber band force vs.
Rubber band force equation.
After you get the rubber band stretched just a little bit it is very spring like.
W elastic potential energy in joules.
F force in newtons.
Elastic potential energy force x distance of displacement.
If you released a rubber band with properties like that it would just stay in the outstretched position until you force into another state.
Displacement 14 12 10 8 f newtons 2 0 0 00 0 02 0 04 0 06 0 08 0 10 0 12 0 14 x meters curve fitting provides the following force vs displacement equation f x 33 55 x 0 4871 where x is in mand f is in n.
A rubber band is a single molecule as is a latex glove.
For example if the pegs are placed such that the band is stretched to 52 inches the force the bands apply to the pegs are 57 6 lbs per inch.
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.
The following figure shows the experimentally obtained measured force vs displacement for a rubber band.
In this case the linear function fitting the straight part of the data gives a spring constant of 17 38 n m.
Elastic potential energy is the stored energy of a compressible or stretchable object like a spring or rubber band or molecule.
Say i have a rubber band wrapped around 2 pegs at a certain distance and at that distance i know the pounds of force per inch it is pulling at.
