Nettet9. apr. 2024 · L – L0 = L0α ΔT, where α is the coefficient of linear expansion of the material. In that case, L = L0 (1 + α ΔT) Hence, thermal stress = F/A = Y (L - L0) / L0 where Y is Young’s modulus of the given material. This can be simplified into Y (α ΔT) / L0 This is considered as the thermal stress formula. NettetWithin certain limits, the force required to stretch an elastic object such as a metal spring is directly proportional to the extension of the spring. This is known as Hooke's law and commonly written: \boxed {F=-kx} F = −kx. Where F F is the force, x x is the length of extension/compression and k k is a constant of proportionality known as ...
