Strain | 2025-2026 |

In the physical sciences, strain measures how much an object under an applied force (stress). It is defined as the ratio of the change in an object's length or shape to its original state.

Strains can happen suddenly (acute) from a fall or heavy lifting, or develop over time (chronic) due to repetitive movements. strain

Common signs include pain, muscle spasms, swelling, and limited movement. In the physical sciences, strain measures how much

In medicine, a strain is an injury to a —the thick, fibrous tissue that connects muscles to bones. Often referred to as a "pulled muscle," it occurs when these tissues are overstretched or torn. Common signs include pain, muscle spasms, swelling, and

The Importance of Strain Measurement in Materials Development

While a strain affects muscles/tendons, a sprain specifically involves ligaments, which connect bone to bone. 2. Engineering & Physics: Material Deformation
