application of the method of sections to determine the shear force

Description:

• WP 961consists of a beam mounted on two supports which is subjected to point loads.
• The beam is cut at one point.
• At that point there is a low-friction hinge with one degree of freedom.
• The force gauge indicates the internal reaction (shear force) at this point on the beam.
• An adjuster nut on the force gauge is used to align the beam horizontally and balance out any deflection.
• The reactions are determined from the static conditions of equilibrium.
• To investigate the effect of the point loads in the beam, it is notionally split into two segments.
• Applying the method of sections, the internal forces and moments are plotted onto the two segments and calculated by way of conditions of equilibrium.
