Young's Modulus: Formula for Calculation

[phymatter]

is there a formula to calculate the young modulous of a system like for resistances in series and parallel ?

 

[Mapes]

Yes, by using Hooke's Law. When samples are placed end-to-end, their displacements add; side-by-side, the forces add.

thanks mapes ! but how will this give effective young's modulous ?
i am a bit confused , please help !

 

[Curl]

if its the same material then Young's Modulus won't change since it is normalized.

How do you express Young's modulus in terms of displacement and force? (Hint: express it in terms of stress and strain first.)
