A piece of copper having a rectangular cross section Mechanical properties of solids class 11 Ncert

A piece of copper having a rectangular cross-section of 15.2mm×19.1mm is pulled in tension with 44,500 N force, producing only elastic deformation. Calculate the resulting strain? (Modulus of elasticity of copper, Y=42×109 Nm−2)

Mam modulus of copper is 1.2×10^11 🤔 by ncert

[@seriously-920]

Mam why we took value of shear modulus of copper why not young's modulus?

[@Krishnathakur-lb3rx]

Mam ase values ko reduce kar sakte h

[@shradha_iitian]

yes you can...but ans mei approx lga dena

[@jayagoswami7847]

But where there is tension, we take young modulus and not shear. Pls tell

[@shradha_iitian]

Young modulus is taken in this solution...Y=long.stress/long.strain

[@jayagoswami7847]

See on pg 242 , in table value 42 is of shear modulus.. The value of Young's modulus is given page number 239 of NCERT , 3 rd column

[@shradha_iitian]

different values are given in different books for this ques.
