Match List I with List II and select the correct answer using the codes given below the lists:
a. Moment of inertia
c. neutral axis
d. Top fibre
1. Tensile stress
2. Modulus of rupture
3. Zero shear stress
4. Zero longitudinal stress
Correct Answer :- A
Explanation : The neutral axis is an axis in the cross section of a beam (a member resisting bending) or shaft along which there are no longitudinal stresses or strains. Therefore, the total amount of force across the cross section must be 0.
Elongation is measured by applying tensile force, or stretching the material in the same manner as described previously, and determining the change in length from original.
The shear stress is zero at the free surfaces (the top and bottom of the beam), and it is bounded by the point of interest and the extreme fiber of the cross section.
