Experiment to investigate stretching a rubber band duration.
Spring constant experiment rubber band.
Weights rubber bands ruler accompanying sheet rubber bands use the weights to find the spring constant of the rubber bands.
Equipment two nearly identical springs long rubber band support stand with a meter stick 50 g mass hanger set of masses from 100 g up to 600 g balance scale science workshop interface with force sensor and rotational motion detector used as a linear sensor.
The first step was to select three rubber bands of differing lengths and widths.
Hooke s law lab report phy 113.
Rubber band spring clamp duration.
K spring constant n m δl change in length of the elastic material m methods this experiment investigated the stretching of rubber bands in an attempt to determine the conditions under which hooke s law applies their action.
We will determine the spring constant for an individual spring using both hooke s law and the properties of an oscillating spring system it is also possible to study the effects if any that amplitude has on the period of a body experiencing simple harmonic motion.
In this case the linear function fitting the straight part of the data gives a spring constant of 17 38 n m.
After you get the rubber band stretched just a little bit it is very spring like.
How to determine the spring constant duration.
The variables of the equation are.
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.
To test whether all elastic objects obey hooke s law.
The minus sign shows that this force is in the opposite direction of the force that s stretching or compressing the spring.
If i assume that i could also rotate this one.
The purpose of this lab experiment is to study the behavior of springs in static and dynamic situations.
How linear is the stress strain relationship for these bands.
Effectively you will have doubled the spring constant by doubling the cross sectional area.
Cut a band into a strip and measure its spring constant.
