3) Bulk Modulus
4) Rigidity Modulus
List -2
A) Lateral strain to linear strain within elastic unit
B) Stress strain with elastic limit
C) Shear stress to shear strain within elastic limit
D) Direct stress to corresponding volumetric strain

Question 7

What will be the relation between E (Young’s modulus of Elasticity) and K (bulk modulus), when Poisson’s ratio is 0.25?

Question 8

The increase in length of a 5 m long wire when the temperature is increased from 20 to 40^oC is (The coefficient of linear expansion for the wire is 0.0005 /^oC)

Question 9

A 4m long bar is subjected to an axial stress of 400 N/mm², If modulus of resilience of bar is 0.2 N/mm², What will be the extension in the bar:

Question 10

If a member is subjected to a compressive stress of 50 N/mm²_, compressive stress of 50 N/mm²_, and tensile stress of 100 N/mm²_, along X, Y and Z directions respectively then the resultant strain along the Z – direction is:

(Take E = 2 x 10⁵ MPa, μ = 0.25)
