Basic civil and mechanical engineering

The deformation in unit original dimension is termed as strain.

• •A.stress.

• •B.Strain

• •C.Force

  •

• D.Youngs Modulus

2.This internal resistance offered by the body to counteract the applied load is called

• stress.

• Strain

• Force

• youngs Modulus

3.When an external force produces elongation of the body in its direction, it is termed as

• •Tensile force.

• .Compresive force

• Stress

• •Starin

4.When an external force causes shortening of the body in the direction of force, it is termed as a…………..

• •A.Tensile force.

• •B.Compresive force

• •C.Stress

• •D.Starin

5.When a body is subjected to two equal and opposite forces acting tangentially across the

resisting section, as a result of which the body tends to shear off across the section, then this tangential force is termed as

• •A.Shear strain

• •B.Shear stress

• •C.A &B

• •D.NONE

6.The change in volume of an elastic body due to external force in unit original volume is called as the

• •A.Shear strain

  •

• B.Shear stress

• •C. Volumetric strain

• •D.NONE

6.The change in volume of an elastic body due to external force in unit original volume is called as the -------

• •A.Shear strain

  •

• B.Shear stress

• •C. Volumetric strain

• •D.NONE

8.………… states that when an elastic material is stressed within elastic limit, the stressis proportional to the strain

• •A.Hooke’s

• •B.Elasticity

• •C.Plasticity

• •D.none

•9.The ratio of the axial stress to the corresponding axial strain, with in elastic limit is called the young’s modulus

• •A.Young’s Modulus

• •B. Shear modulus

• A and B

• NONE

10.The ratio of the shear stress to the corresponding shear strain is a constant, which is called shear modulus Then symbol of shear modulus is ---------

• G

• .C

• C

• R
