Witryna4 wrz 2024 · In SFD and BMD diagrams Shear force or Bending moment represents the ordinates, and the Length of the beam represents the abscissa. Consider the left or the right portion of the section. Add the forces (including reactions) normal to the beam on the one of the portion. If the right portion of the section is chosen, then the force acting ... In solid mechanics, a point along a beam under a lateral load is known as a point of contraflexure if the bending moment about the point equals zero. In a bending moment diagram, it is the point at which the bending moment curve intersects with the zero line (i.e. where the bending moment reverses direction along the beam). Knowing the place of the contraflexure is especially useful when designing reinforced concrete or structural steel beams and also for designing bridges.
