Description

This apparatus has been designed for use in either the classroom or laboratory and may be used to show that in a beam subject to transverse loads, at any section of the beam:

1. The SHEARING FORCE is the algebraic sum of the transverse components of the forces to one side of the section.
2.  The BENDING MOMENT is the algebraic sum of the moments of the forces to one side of the section.

The beam is hinged at a typical transverse section and loads may be applied at varying positions on the beam.

For the purposes of obtaining equilibrium, balancing forces are applied at the hinge point by suitable masses attached to cords passing over ball bearing pulleys.

Complete with masses.
