WebThere is a point force acting in the x axis that causes the beam to deflect in the y direction. (Since we're assuming the beam is homogenous and isotropic, there is no preference for … The following model applies to columns simply supported at each end (). Firstly, we will put attention to the fact there are no reactions in the hinged ends, so we also have no shear force in any cross-section of the column. The reason for no reactions can be obtained from symmetry (so the reactions should be in the same direction) and from moment equilibrium (so the reactions should be …
