Hooke s law lab report phy 113.
Spring constant experiment rubber band.
How linear is the stress strain relationship for these bands.
Phy 113 hooke s law springs objective the objective of this lab was to test hooke s law by measuring the spring constants of different springs and spring.
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.
The minus sign shows that this force is in the opposite direction of the force that s stretching or compressing the spring.
The variables of the equation are.
The purpose of this lab experiment is to study the behavior of springs in static and dynamic situations.
Effectively you will have doubled the spring constant by doubling the cross sectional area.
Rubber band spring clamp duration.
The first step was to select three rubber bands of differing lengths and widths.
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.
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.
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.
To test whether all elastic objects obey hooke s law.
General physics phy 112 academic year.
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.
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.
If i assume that i could also rotate this one.
