application of the method of sections to determine the bending moment

Description:

• WP 962consists 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 bending moment occurring at the section is recorded by a force gauge acting on a fixed lever arm.
• An adjuster nut on the force gauge is used to align the beam horizontally and balance out any lowering.
• 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.
