Numerical Response Questions | Physics 11 Chap 7: Deformation of Solids | National Books Foundation

This section provides a comprehensive collection of Numerical Response Questions for Chapter 7: Deformation of Solids from the Physics 11 syllabus by the National Books Foundation (NBF). Tailored for students under the Federal Board of Intermediate and Secondary Education (FBISE), Islamabad, the questions cover crucial topics like:

Stress: The force exerted per unit area within materials.
Strain: The deformation experienced by a solid when stress is applied.
Elastic Modulus: The measure of the stiffness of a material and its ability to return to its original shape after deformation.
These numerical questions are designed to challenge and enhance students' understanding of the physical properties of solids under various forces and stresses. The resource is ideal for exam preparation, providing both practice and a deeper insight into core concepts of Physics.

I sincerely apologize. In the first numerical, I kept referring to the shear Modulus as Shear Strain, which is incorrect. it was shear Modulus not Shear Strain. I mentioned it several times in my explanation.
I couldn't fix this issue as it was uploaded.
I sincerely apologize. This is purely a human error and slip of tongue.

sir apne first question me shear modulus ka formula likha fir shear stress and shear strain ki values dali th, fir ap shear modulus ko shear strain khete rahe or shear modulus ki jaga shear strain ka formula derive kia khudse (which is acceptable, as it wasnt given beforehand) lekin shear modulus ki jaga apne shear strain q likha? is tarah to do dafa shear strain agia, lekin fir bh ans book wala agia???

Aoa Sir Good explaination 👍🏻but 3 numerical may jb hm delta Lb ki value likh rhy thy 1.2×10^ -3 so ap nay total delta L ki liki 1.3 ... Wali
agr 1.2... wali daly then ans 7.2× 10 ^ -3 ata 7.8... ki jaga and overall last pr bi ans 0.035 ata.
Is ka bta dain sir
