Question

Dimension formula for elastic strain will be?

• A. $$M ^ 0 L ^ 0 T ^ 0$$
• B. $$M ^1 L ^ {-1}T ^ {-2}$$
• C. $$M ^ 0 L ^ 0 T ^ {-1}$$
• D. None of these

Answer 1

Answer:

$$M ^ 0 L ^ 0 T ^ 0$$

Strain can be defined as the ratio of change in an object's dimension to its original dimension. This can be expressed as$strain = \delta L/L$ $or (\delta A)/A$ $or (\delta V)/V$ . The dimension formula for elastic strain is $M ^ 0 L ^ 0 T ^ 0$ which unitless quantity and has no dimension.
