How to find strain in simple cantilever beam

[ashunitk]

Hello to everyone,
my question is how to find strain in rectangular cantilever beam applying point load at some point. I am not getting formulas for that..Please save me from this. Its very urgent for me.

Hi ashunitk, welcome to PF. Are you able to find the stress? Hooke's Law links stress and strain.

I am not cleared with wat u have given answer about how to find strain. Can u just send me formula to find strain of cantilever beam of rectangular cross section having point load at its free end with description of formula.

Are you looking for something like http://www.efunda.com/formulae/solid_mechanics/beams/casestudy_display.cfm?case=cantilever_endload"? And for uniaxial stress, the strain is just the stress divided by the Young's elastic modulus.

Ya what u said is right but that is general ..but i want specific to cantilever beam.As u said strain equals to stress by young's modulus.Where stress equals to force by area.can u send some document regarding to my mail id if so my id is zoom143.ashwin@gmail.com...
