MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Poisson ratio depends on

Lateral strain

Stress

Material of specimen

None

Answer explanation

It is a material property that describes how a material deforms laterally when stretched or compressed longitudinally.

Stress is a ___ quantity

Vector

Scalar

Tensor

None of the above

MULTIPLE CHOICE QUESTION

30 sec • 1 pt

If a piece of material neither expands nor contracts in volume when subjected to stresses, then the Poisson’s ratio must be?

0.5
1.0
0.0
-0.5

Answer explanation

If a material does not change in volume under stress (i.e., no volumetric strain), this implies it is perfectly incompressible.

In such a case, the Poisson's ratio (ν) is:0.5

When tensile stress is applied axially on a circular rod its

diameter decreases

length increases

Volume decreases

Both A and B

Answer explanation

When tensile stress is applied axially on a circular rod, the following occurs:

  1. Length increases — due to elongation along the axis (longitudinal strain).

  2. Diameter decreases — due to lateral contraction (lateral strain).

which one of the following is a unit less factor

stress

strain

young's modulus

both b and c

MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Which of the following best describes shear force in a material?

A force acting perpendicular to the cross-section causing elongation

A force that changes only the volume of the material

A force acting parallel to the cross-section causing layers to slide

A compressive force that shortens the material

Answer explanation

  • Shear force acts parallel to the cross-sectional area of a material.

  • It causes internal layers to slide past each other

  • Unlike normal stress (which causes elongation or compression), shear stress results in shape distortion (change in angle, not volume).

  • This force is crucial in materials like bolts, rivets, or beams, which resist sliding failure.
