Webb22 mars 2024 · Stiffness” refers to the ability of a structure or component to resist elastic deformation. It is determined by the force or moment required to produce a unit of strain. In terms of rotational stiffness, it is represented by “k” and can be calculated as “k = M / θ”, where “M” is the applied torque and “θ” is the rotation angle. Webb12 nov. 2024 · Equation and Units. The equation for Young's modulus is: E = σ / ε = (F/A) / (ΔL/L 0) = FL 0 / AΔL. Where: E is Young's modulus, usually expressed in Pascal (Pa) σ is the uniaxial stress. ε is the strain. F is the force of compression or extension. A is the cross-sectional surface area or the cross-section perpendicular to the applied force.
