The columns whose slenderness ratio is less than 80, are known as
A. Short columns
B. Long columns
C. Weak columns
D. Medium columns
The poisson's ratio is related to modulus of elasticity as Y=3B(1−2σ). Since stress is same for Y and B, we get, dL/L=dV/3V(1−2σ)⟹dV=3V(dL/L)(1−2σ)
As σ is increased, dV decreases.
The correct option is (b)
