Find the force constant fron the graph
Hi all

Find the force constant force the graph
k = 1/0.27 = 3.70 n/m ( is this ok )
plese I want your help

I don't have a clue of what you are trying to do... What is that graph about? What are the axes? What graph is drawn on it?

graph between Extenstion of spring for load and load W (N)

Well, the spring constant is given by the gradient. So, find the gradient and that will be the answer.

$Gradient = \dfrac{y_2 - y_1}{x_2 - x_1}$

e^(i*pi)

You graph isn't working, it requires me to register in order to see the image.

From what I can gather from your units and general knowledge your force constant is going to be the Force/distance (does this happen to be a question on Hooke's Law by that way?)

Your force constant is going to be the gradient on the graph of Force (y axis) against distance (x axis)
