gradient of f/extension graph multiplied by length/area gives youngs modulus-EXAM 2MO

i know the gradient of force/extension graph is k but if you multiply that by length/area do you get young modulus?.
Y=FL/A(deltaL)

young's modulus = stess/strain

sress = fource/area
strain = delta length (change in length)/original length

hope it helped

yes.force = ke

hence k = f/e

but Y =FL/Ae ------------------------------2

looking at eqn 2 you can see that it can be reaaranged to give:

Y = kL/A where k =F/e

so yes gradient of force extension multiplied by L/A gives Young modulus
