Question

What is the spring constant of a spring that compresses 0.27 m when a

force of 589 N is applied to it?

a. 160 N/m

b. 21 N/m

c. 2200N/m

d. 3000 N/m​

Answer 1

Answer 2

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

0.020

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.
