Y = distance to point from neutral axis (m, mm, in) The stress in a bending beam can be expressed as Δ B = maximum deflection in B (m, mm, in)Į = modulus of elasticity (N/m 2 (Pa), N/mm 2, lb/in 2 (psi))ī = length between B and C (m, mm, in) Stress L = length of beam (m, mm, in) Maximum DeflectionĪt the end of the cantilever beam can be expressed as M A = maximum moment in A (Nm, Nmm, lb in) F = single acting force in B (N, lb) Maximum Moment
