Elastic Properties of Deflected Beam Apparatus

Category:

Apparatus consists of a mild steel beam 2.5cm x 3mm in cross section and 100cm long, pinned to two supports 70cm apart situated symmetrically. One of the ends can be fixed or given a known slope by applying a known moment at the end with the help of suspended loads. At the other end also, a known moment can be applied. Vertical loads can be applied at various points along the span of the beam.

A dial gauge with 25mm travel (with a magnetic base) may be supplied with the apparatus. Apparatus to be supplied should be complete with a supporting stand and a set of weights.

  • This equipment is part of a ranged to both, demonstrate and experimentally confirm basic engineering principles. Great care has been given to each item so as to provide wide experimental scope without unduly complicating or compromising the design. Each piece of apparatus is self-contained and compact. Setting up time is minimal, and all measurements are made with the simplest possible instrumentation, so that the student involvement is purely with the engineering principles being taught.
  • A complete instruction manual is provided describing the apparatus, its application, experimental procedure and typical test results.
  • The bench mounted apparatus has a steel base with support at ends.
  • The supports can be fitted with knife edges or clamp plates.
  • A steel beam and two load hangers are supplied together with two dial gauges for measuring beam deflections and slopes.
