Question

Which type of stress is shown in the image?

Answer 1

Answer:

The type of stress shown in the figure is compression stress.

Explanation:

The Stress that is responsible for the change in shape of the material is called as Compression Stress. The compression stress also reduces the  volume of the material. Compression force is responsible for compression stress.

When compression stress is applied on a brittle material ,it shatters into small pieces due to the sudden release the energy stored in the material. However when Compression stress is applied on a ductile material the material undergoes compression. The unit compression stress is Pascal(Pa) or $N m^{2}$.

Mathematically, Compression stress can be calculated by using

$\sigma=\frac{F}{A}$

Where  

F= Compression force

A= unit area

$\sigma$= compressive stress
