Shearing Force Apparatus
Product Code : JA-ELA-5518
The Shearing Force Apparatus (SKU JA-ELA-5518) is a bench-mounted beam experiment supplied by JaincoLab for showing the internal shearing force at a section of a loaded beam. The beam is made in two parts joined by a pair of ball-bearing rollers running in flat vertical tracks. At the cut, an underslung tension spring resists the bending moment and an overhung spring balance supplies, and measures, the vertical shearing force. The beam is simply supported on end bearings, and weight hangers can be placed anywhere on either side of the joint.
Specifications
The beam, measuring springs and loading arrangement listed are shown below.

Frequently asked questions
How is the shear force measured?
By an overhung spring balance at the joint of the split beam.
Why must the longer side carry a net load?
Because of the mechanical arrangement, there must always be a net downward load on the longer side of the split beam.
What is the hinged metal strip for?
It simulates the loading pattern of a panelled girder for the influence-line experiment.
