Spring Constant Experiment Rubber Band

After you get the rubber band stretched just a little bit it is very spring like.

Spring constant experiment rubber band. 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. Weights rubber bands ruler accompanying sheet rubber bands use the weights to find the spring constant of the rubber bands. Rubber band spring clamp duration. 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.

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. How to determine the spring constant duration. How linear is the stress strain relationship for these bands. 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.

Cut a band into a strip and measure its spring constant. The minus sign shows that this force is in the opposite direction of the force that s stretching or compressing the spring. Hooke s law lab report phy 113. Experiment to investigate stretching a rubber band duration.

General physics phy 112 academic year. In this case the linear function fitting the straight part of the data gives a spring constant of 17 38 n m. Effectively you will have doubled the spring constant by doubling the cross sectional area. 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.

If i assume that i could also rotate this one. To test whether all elastic objects obey hooke s law. The first step was to select three rubber bands of differing lengths and widths.
