The Uses
To use a Spring, You need to know these things : yield point, elastic limit, and proportional limit. But where can we find, well for that science use Load - Extension Graph.
The load-extension graph represents the relationship between the load (force) applied to a material and the extension (deformation) it experiences. Key points like yield point, breaking point, elastic limit, and crushing point can be identified on the graph, providing insights into the material's behavior.
The slope of the load-extension graph is crucial for determining Young's modulus, particularly for materials following Hooke's law. Young's modulus is a measure of stiffness or elasticity of a material.

Answers :
The gradient would be the extension per unit load.
The area under a force-extension graph represents the work done in stretching a material.
102-80 = 22cm
2.5*0.04 = 0.1Nm
0.1/0.12 = 0.83N.
What is the gradient of a load extension graph?
What is the area under extension load graph?
A piece of elastic cord is 80cm long. when it is stretched ,its length increase to 102cm.what is its extension.
A spring requires a load of 2.5 N to increase its length by 4.0 cm.the spring obeys hookes law. what load will give it an extension of 12.0 cm?
