A beam is a structural element that primarily resists loads applied laterally to the beam's axis (an element designed to carry primarily axial load would be a strut or column). Its mode of deflection is primarily by bending. The loads applied to the beam result in reaction forces at the beam's support points. The total effect of all the forces acting on the beam is to produce shear forces and bending moments within … WebFeb 16, 2024 · Engineering beam theory was used to inform the analysis of maize stalk strength. The equation for a simple beam in bending ( Howell, 2001 ) states that tissue stress (σ) depends on the applied moment ( M ), the area MOI, and the distance between the neutral bending axis and the point at which the stress is being measured ( c ) as …
