Question

The ratio of the change in dimension at right angles to the applied force to the initial dimension is known as.

Answer 1

The ratio of the change in dimension at right angles to the applied force to the initial dimension is known as Lateral strain.

Here,

We have to find, The ratio of the change in dimension at right angles to the applied force to the initial dimension .

What is Lateral strain?

Whenever the bar is subjected to the axial load ,there will be decrease in the dimensions of the bar in the perpendicular direction of loading. Therefore lateral strain is defined as ratio of decrease in the length of the bar in the perpendicular direction of applied load to that of the original length (gauge length).

⇒ e = dB/B or dD/D

where, e= lateral strain

Now,

The ratio of the change in dimension at right angles to the applied force to the initial dimension is known as Lateral strain.
