Product Description

Description of Deflections of Beams

Two movable vertical beam supports allow the fixing of knife-edges to their tops to create a simply supported arrangement for the study of Deflections of Beams. Each support can be moved anywhere within the working area of the Universal Frame and Stand and allows a variety of beam spans to be achieved. 

Two steel beams are supplied, each having a different thickness, thus allowing the effect of beam thickness and length on deflection to be studied.  Apart from the large difference in second moments of area (nearly 1 to 4.5) it will be found that the stiffer beam is more accurate experimentally, while the more flexible beam exaggerates the deflected shape and is visually instructive.

Three load hangers supplied ensure a variety of loads can be applied to the Deflections of Beams. Each hanger is attached to the beam via beam clamps. Each clamp can be positioned anywhere along the working length of the beam, and can be quickly and easily removed and re-positioned. A set of calibrated test weights and load hangers creates the loads.

Experimental Capabilities of Deflections of Beams

  1. Study of the general formula for beam deflections in bending in the form y= c. WL3 / EI
  2. Verification of the effect of changing the length and thickness of beams
  3. Study the way the ‘constant’ c is affected by the type and position of the load
  4. The principle of superposition
  5. To compare the measured and theoretical values
