Two basic types of stress are?

• A. Shear and Torsion
• B. Compression and Tension
• C. Bending and Shear
• D. Torsion and Compression

Answer: (B)

When a material is loaded along its length, the stress that develops across its cross-section is called normal stress, and it can be either tensile or compressive. Tensile stress occurs when the force pulls the ends of the material apart, causing elongation, with stress defined as sigma = F/A. Compressive stress happens when the force pushes the ends together, causing shortening. These two represent the simplest, opposing forms of normal stress under axial loading. Other stress patterns like bending, shear, or torsion involve different distributions of internal forces (for example, bending creates tension on one side and compression on the other, shear involves parallel sliding forces, and torsion produces shear stresses along the cross-section). But for straightforward axial loading, the two basic types are tension and compression.
