If a force F (N) is applied to compress a spring, its displacement x (m) can often be modeled by Hooke's law:
F = kx
where k = the spring constant (N/m). The potential energy stored in the spring U (J) can then be computed as
Five springs are tested and the following data compiled:
F,N
11
12
15
9
12
x,m
0.013
0.020
0.009
0.010
0.012
Use MATLAB to store F and x as vectors and then compute vectors of the spring constants and the potential energies. Use the max function to determine the maximum potential energy.
