Description
The Beam Apparatus allows an extensive range of experiments to cover virtually all course requirements relating to bending of beams. The basic unit provides facilities for supporting beams on simple, built-in and sinking supports, applying point loads, and measuring support reactions and beam defl ections. It includes five different test beams. A pack of ten additional specimen beams is available for further experiments. The Beam Apparatus can be used for an almost limitless number of experiments ranging from determination of the elastic modulus for beams of diff erent materials, through to studies of continuous beams with any loading. Great care has been taken at the design stage to ensure maximum flexibility and ease of use. The main frame of the apparatus consists of an upper cross-member carrying graduated scales and two lower members bolted to T-legs to form a rigid assembly. The three load cells and cantilever-support pillar slide along the lower members and can be clamped fi rmly in any position. The load cells have direct digital readout and each is fitted with a hardened steel knife edge which can be adjusted to set the initial level or to simulate a sinking support. Locking pins can convert each load cell to a rigid support when required.The cantilever support is a rigid pillar with a sturdy clamping arrangement to hold the beamswhen built-in end conditions are required. Four weight hangers and a set of weights are supplied to apply static loads. Three digital indicators measure all beam defl ections. The indicators mount on magnetic carriers that slide along the upper cross-member. The indicators, carriers, load cells and weight hangers all have cursors that register on the scale (located on the upper cross-member) to ensure easy, accurate positioning. All digital indicators and load cells have sockets and cables for connection to optional Versatile Data Acquisition System. The standard test beams are in three thicknesses and include three diff erent materials. They are suitable for the complete range of experiments covering 
different loading and support confi gurations. The optional set of beams provide for experiments on diff erent types of beam including compound, channel and non-uniform 
beams of various materials. For quick and reliable tests, optional gives accurate realtime data capture, monitoring and display, calculation and charting of all important readings on a computer (computer not included).
Learning outcomes

•  Verification of the bending equation
•  Determination of fl exural rigidity and elastic modulus (Young’s modulus)
•  Verification of static equilibrium
•  Deflection of beams on two simple supports with point loads
•  Reciprocal properties for loads and defl ection
•  Simple and propped cantilevers with any loading

•  Bending characteristics of a brass/steel compound beam, with and without shearing connection between the two layers
•  Equivalent sections, characteristics of a metal-faced wooden beam
•  Defl ections on a non-uniform (tapered) beam or cantilever
