Tesca 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 deflections. 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 different 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 firmly 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 beams when  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 deflections. 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.  

The standard test beams are in three thicknesses and include three different materials. They are  suitable for the complete range of experiments covering different loading and support configurations.  The optional set of beams provide for experiments on different types of beam including compound,  channel and non-uniform beams of various materials.
