ANALYSIS AND EXPERIMENTAL VERIFICATION OF BEAM DEFLECTIONS, CASE SIMPLY SUPPORTED AND A CANTILEVERED BEAM PROPPED AT THE FREE END.

ABSTRACT

The main objective of this project was to analyze and experimentally verify beam deflections. The beam was subjected to two different end conditions namely, simply supported and end fixed and the other propped. Different loading situations were applied to the beams under these end conditions. The loading situations included; point loads, point loads and couple, distributed loads and a combination of the three.

The process of verification involved calculation of the theoretical values of deflections using the different derived formulae of deflection. The experimental values of were taken from dial gauge readings and converted to the required units (meters). The two sets of results were then tabulated alongside each and compared. Graphs of load against deflection were plotted to aid with the comparison and analysis.

From the results obtained the experimental and theoretical values of deflection showed good correlation but for a few discrepancies. These little errors  were a result of errors  from the experiments carried out which include; end conditions not being achieved perfectly, assumption that that the point load and couple acted at a point, human errors in taking of the readings and propagation of these errors in calculations among others.

Generally the project was a success. The objectives set out were achieved. At the end of the project recommendations on how to improve the experiments carried out.
