Question

Which of the following statements are correct?
1. Strain in the direction of applied stress is known as longitudinal strain.
2. Tensile stress results in tensile strain in linear and lateral directions.
3. Strains in all directions perpendicular to the applied stress are known as lateral strain.
4. Ratio of change in volume to original volume is known as volumetric strain.

• A. $1,2$ and $3$ only
• B. $1,3$ and $4$ only
• C. $3$ and $4$ only
• D. $1,2,3$ and $4$

Answer 1

The correct option is B $1,3$ and $4$ only

• Longitudinal direction is that direction in which force or stress is acting.
• Due to tensile stress, longitudinal strain will be tensile but the lateral strain will be compressive.
