Answered by SandraRobin

Young's modulus is the ratio of longitudinal stress and longitudinal strain. Denoted by 'Y'. Y= Fl / A dl

saka82411: No it is wrong. It is denoted by 'q' not'y'.

SandraRobin: really? oh... our teacher taught us 'Y' that's why :D

ammu143Kochu: It's okk tq for the helping mind

SandraRobin: thank you for ur answer. Would u please check my question again... i've asked something else..

saka82411: I checked it.

Answered by saka82411

Young's modulus is defined as ratio of longitudinal stress to the ratio of longitudinal strain.

q=F/A÷dl/l.
q=f.l/a.dl
Longitudinal stress=F/A
Longitudinal strain=I/L.

ammu143Kochu: Thank saka for helping me

saka82411: OK.
