Problem Statement

What is stress vs strain?

Step-by-Step Explanation

Stress measures internal force per area, while strain measures deformation relative to original size.

  1. Identify what the question is asking. In Materials Science, this usually means naming the known quantities, the unknown quantity, and the concept that connects them.
  2. Write the relevant definition, rule, or relationship before substituting numbers or manipulating symbols.
  3. Work one step at a time and keep units, signs, and restrictions visible.
  4. Check whether the answer makes sense in the original context.

Key Formula

σ=FA\sigma=\frac{F}{A}

Final Answer

Stress measures internal force per area, while strain measures deformation relative to original size. The reliable strategy is to start from the definition, apply the correct rule carefully, and then interpret the result in plain language.
