Force Extension Graph. From Equation 2 if Hookes Law is obeyed by this spring then the force F applied to the spring is direction proportional to the extension of the spring. Greater the value of K the stiffer the spring is.
FkΔL K Spring constant. Graphs that show the variation of stress with strain have the same shape as the force-extension graphs on page 31. Dec 14 2020 You started to find k from force and extension.
The diagram shows a force-extension graph for a rubber band.
5 Calculate the extension of spring using the data recorded in the table. From Equation 2 if Hookes Law is obeyed by this spring then the force F applied to the spring is direction proportional to the extension of the spring. Unit for K Nm. Graph of F against ΔL is a straight line of gradient k through the origin.
