If you use STAAD (Structural Analysis and Design) software to model and analyze beams and columns, you might wonder how to interpret the bending moment and shear force diagrams that the program ...
In general Load would have value and location. The sign of the value can indicate whether it is pointing upwards, or downwards in the case of force, or clockwise/anticlockwise in case of moment. While ...
CONCLUSION: Shear stresses play an important role in the Euler-Bernoulli theory for the bending of beams when shear force resultants exist at a given cross section.
