Rubber Band Force Constant

In this case the linear function fitting the straight part of the data gives a spring constant of 17 38 n m.

Rubber band force constant.

After you get the rubber band stretched just a little bit it is very spring like. If you had rubber bands of the same cross sectional area then the one that stretches the least also. For example a thicker rubber band should have a larger spring constant due to its larger cross sectional area. 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.

When a rubber band is stretched some of the network chains are forced to become straight. In this experiment you can check this prediction and investigate the way in which hooke s law applies to rubber bands. The question asks to determine the force constant k k. Yes and no rubber bands have a linear proportionality between the load and extension only till a certain limit is reached differs from the elastic limit of a spring for instance a 10 increase in stretching force will make a typical rubber band 10 longer however when rubber bands are stretched to twice their original size or more the.

If i assume that i could also rotate this one. From the experiment i did my force was equal to 0 0686n 0 00196n and my x rubber band stretch was equal to 0 003m 0 002. The variables of the equation are. The rubber band that stretches the least for a given weight applied force has the greatest spring constant.

A rubber band is a single molecule as is a latex glove. 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 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.
