One of a range of experiment modules that fit to the Structures platform STS1 (available separately), this product helps students to understand how loads affect the bending moment in a beam.
Students apply loads to hangers suspended along the beam, held between two supports. One support allows rotational movement only, acting as a pinned support. The other support allows translational movement, acting as roller support. A load cell at the cut at the mid-span of the beam measures the bending moment due to the load. The beam has a central span with an overhanging end, so that students can create both positive and negative bending moments (‘sagging’ and ‘hogging’).
Each support includes pointers that work with the scale on the platform for accurate positioning. Students use textbook equations to predict the bending moments due to the load, compare them with measured results, and learn how to create the influence line and bending moment diagrams. This helps confirm the reliability of the textbook equations and the accuracy of the experiment results.
This product includes a uniformly distributed load (UDL) that may be applied across the span of the beam for comparison of results with a single point load.
The load cell connects to the USB interface hub of the Structures platform for computer display and data acquisition.
