Much appreciated sir,i have fully understood it with in a minute 🙏💫

[@Xerxes003]

Thank you sir ✨~

[@hamoodydamdam5480]

Thank you very much

[@7gbfun960]

sir there is a mistake in volumetric strain formula ev=3e(1-2u)

[@saikishanrepalle3793]

Ashish Adiley are you sure about that?

[@Amar_2300]

Ashish Adiley you are wrong

[@manojpolawar7195]

bhai we have applied load in one direction only so its correct

[@kabutar7998]

Ashish bhai ap galat Bata rehe ho

[@billakarthik5940]

For uniaxial load in volumetric strain ev={ [sigma(p/A)/young Modulus (E)]× (1-2m)} From Hooke's laws stress directly proportional to strain Sigma=young Modulus E× strain Strain(e)=sigma÷ Young's modulus E So volumetric strain(ev) in uniaxial load={strain(e)×1-2m}

E=200X10^-3 N/mm^2

Your answer for dv is 4500 but its wrong. lnew=6000+3=6003 tnew=20-0.0025=19.9975 bnew=150-0.01875=149.98125 Vnew=lnew X bnew X tnew =18004498.03 dV=Vnew-Vold=18004498.03-18000000=4498.031391

you should have solve the solution before in a sheet and u just need to explain because lot of time is being wasted in writing
