Shear Force and Bending Moment Apparatus AZA1336
Shear Force and Bending Moment Apparatus AZA1336
The Shear Force and Bending Moment Apparatus is a precision educational and laboratory instrument designed to demonstrate fundamental principles of structural mechanics in beams subjected to transverse loading. Suitable for both classroom instruction and laboratory experimentation, the apparatus provides a clear, visual understanding of shear force and bending moment relationships along a beam.
The apparatus allows students and engineers to verify that, at any section of a loaded beam:
-
The shear force is equal to the algebraic sum of the transverse components of all forces acting on one side of the section.
-
The bending moment is equal to the algebraic sum of the moments of all forces acting on one side of the section.
Description
The beam is hinged at a representative transverse section, enabling direct observation of equilibrium conditions. Loads can be applied at variable positions along the beam span to study their influence on shear force and bending moment distribution.
For achieving equilibrium, balancing forces are applied at the hinge point using calibrated masses suspended via cords passing over smooth-running ball-bearing pulleys. This arrangement ensures accurate force transmission and repeatable experimental results.
The apparatus is supplied complete with a full set of masses, making it ready for immediate use in teaching and demonstration environments.
