Tension (physics)

Tension in Physics: Tension is a nonnegative vector quantity. Zero tension indicates slack. Tension in a string is constant along its length. Vibrating strings’ frequencies depend on tension. Curvature in a string causes a net force and acceleration. Tension in 3D materials is similar to negative pressure. A rod under tension elongates. Stress = axial force / crosssectional area is crucial in engineering. Stress is a 3×3 matrix called a tensor. A scalar analogous to tension can be obtained by taking the trace of the stress tensor. Strings in modern physics have tension. Strings in modern string theory possess tension. Energy in strings is proportional to their length. Tension in strings is independent of stretching. Strings are analyzed in terms of their world sheet. Equilibrium and Net Force: Equilibrium in a system means the sum of all forces is zero. Tension in a string equals the weight force in equilibrium. Equilibrium is maintained when tension equals the weight force. A net force exists when the sum of all forces is not zero. Acceleration and net force coexist. Net force causes changes in velocity. In an inextensible string, Hooke’s law applies. Solid Mechanics: Branch of physics. Study of behavior of solid materials. Deals with deformation and failure of solids. Includes topics like elasticity and plasticity. Important in engineering and material science. Articles with Short Description: Provides a brief overview. Helps readers understand content quickly.
