Force Constant Of Rubber Band

When a rubber band is stretched some of the network chains are forced to become straight.

Force constant of rubber band.

In this case the linear function fitting the straight part of the data gives a spring constant of 17 38 n m. 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. After you get the rubber band stretched just a little bit it is very spring like. 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.

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. Since we heated the band up h q 0. The ultimate strength is measured by breaking the material. The elongation of the rubber band is the product of these two forces this you measure with a ruler.

When the rubber band is pulled by a force of 9 8 n how far will it stretch and what is its potential energy. The tension in the rubber band is the component of these two forces. If i assume that i could also rotate this one. The greater the weight the.

This can be done reversibly so that. The variables of the equation are. The rubber band that stretches the least for a given weight applied force has the greatest spring constant. 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.

If you had rubber bands of the same cross sectional area then the one that stretches the least also has the greatest elastic modulus. A rubber band has a spring constant of 45 n m. 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. The work w is f d p v the p v term is very small and h q f d p v f d p v q.
