Great question. Young's modulus is a material/intrinsic property of the material and is constant regardless of the change in dimension of the test specimen. Y = Stress/ Strain = F*L/A*dl Assume if you change the L to L/2 and r to r/2 i.e A to A/4 and Force required to get the same extension is also F/2,...

Great question. Young's modulus is a material/intrinsic property of the material and is constant regardless of the change in dimension of the test specimen.

Y = Stress/ Strain = F*L/A*dl

Assume if you change the L to L/2 and r to r/2 i.e A to A/4 and Force required to get the same extension is also F/2, above equation becomes

Y = 4*F*L/4*A*dl = F*L/A*dl ( Same as above)

Happy learning!!!

What should be the fees for class XI and xii physics per class in Bhubaneswar?

According to me, the best fee will be the changed study pattern of the students from rote to conceptual and being able for themselves to choose what they actually want to do after 12th ( not necessarily engineering or MBBS). Thanks.
