Concept explainers

Solid Mechanics

Engineering mechanics is a branch of science that deals with forces causing bulk motion in bodies and the effect that these forces cause on the bodies. Engineering mechanics does not deal with the internal changes that occur on account of these external forces. The internal effects in a body or a material under the action of external forces are studied in a new branch of science called solid mechanics, the strength of materials, or the mechanical behavior of engineering materials.

Question

### Stress and Shear Stress in Materials

**Normal Stress (\(\sigma_A\))**

- \(\sigma_A = -20 \text{ ksi}\)

This value indicates a compressive stress of 20 ksi. In engineering, negative values typically represent compressive stress, meaning the material is being compressed.

**Shear Stress (\(\tau_A\))**

- \(\tau_A = +10 \text{ ksi}\)

This value indicates a shear stress of 10 ksi. Positive values usually signify that the material experiences shear in a specific direction.

These values are critical in evaluating the structural integrity and failure conditions of materials under different kinds of loadings. Understanding the behavior of materials under such stresses aids in the design and analysis of various engineering structures.
