The deformation of the bar, per unit length in the direction of the force (i.e. δl/l) is known as primary strain or linear strain.
When a change in length takes place, the strain is known as linear strain.
11) When a change in length takes place, the strain is known as

Answer is:
linear stress to linear strain
Explanation:
Young’s Modulus is defined as ratio of Normal Stress to Longitudinal Strain. Young’s Modulus is usually denoted with letter E. Young’s Modulus is also called as Modulus of Elasticity.
Answer is:
shear stress to shear strain
Explanation:
Modulus of rigidity may be defined as the ratio of shear stress to shear strain.
Answer is:
half
Explanation:
The deformation of a bar under its own weight = Wl^2 / 2E.
whereas Deformation under direct load = Wl^2 / E.
therefore The deformation of a bar under its own weight is half (1/2) the deformation if the same body is subjected to a direct load equal to the weight of the body.
Answer is:
one-third
Explanation:
Elongation of bar = (wl^2/2E).
Elongation of conical bar = (wl^2/6E).
Conical bar/Prismatic Bar.
= (wl^2/6E) / (wl^2/2E),
=1/3.
