The point of contraflexure is where
WebbThe point of contraflexure (PoC) occurs where bending is zero and at the point of change between positive and negative (or between compression and tension). In a beam that is … Webb8 dec. 2011 · Consequently, it is not always sufficient to investigate the points of zero shearing force when determining the maximum bending moment. At a point on the beam where the type of bending is changing from sagging to hogging, the bending moment must be zero, and this is called a point of inflection or contraflexure.

WebbThe position of the zero moment point is affected by the referred mass and inertia of the robot's torso, since its motion generally requires large angle torques to maintain a satisfactory dynamical postural stability. One approach to solve this problem consists of using small trunk motions to stabilize the posture of the robot. WebbThe beams also bend in a two-fold curvature to resist the bending, with points of contraflexure roughly in the middle of the span. The overall shear racking of the frame is caused by the accumulated bending of the columns and beams. According to Fig. 3.4b, the deflected shape caused by this component has a shear deflection structure.
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.
