Transverse Vibration of Beam Lab Report Introduction This experiment aimed to study the forced damped transverse vibration of a beam and verify Dunkerley’s empirical formula. According to Dunkerley’s empirical formula‚ 1f2=1fb2+1fω2 where f referring to the natural frequency of heavy beam with central load fb referring to the natural frequency of heavy beam only fω referring to the natural frequency of light beam with central load M By using the results of light damping‚ Dunkerley’s

Mechanics Abstract This report has been written to describe an experiment performed on a channel section examining the stiffness of the beam through two differing types of deformation – curvature and deflection. The aim of the experiment was to determine the value of the flexural rigidity (EI) in two different ways; using the curvature‚ k‚ and the mid-span deflection. The testing method used for the experiment is described. The experiment found that the EI values calculated were as follows: - EIcurv

moment is simply defined as “the algebraic sum of the moments of all the forces which induces bending of an element” (1). The aim of this assignment is to work out the bending moment in a simply supported beam when different concentrated loads are applied to it. A simply supported beam is a structure‚ usually with a straight profile supported at the ends‚ often pinned on one side and simply supported or on a roller on the other. There will be three series of loads applied to this beam & the findings

VIBRATION - I Aim: To find the natural frequency of transverse vibration of the cantilever beam. Apparatus required: Displacement measuring system (strain gauge) and Weights Description: Strain gauge is bound on the beam in the form of a bridge. One end of the beam is fixed and the other end is hanging free for keeping the weights to find the natural frequency while applying the load on the beam. This displacement causes strain gauge bridge to give the output in milli-volts. Reading of the

of a beam subjected to increasing bending moments and to discover the stress distribution in the beam for both the direct and shear stresses. This was done by applying a known load to the beam and recording the deflection of the loading points. These readings were then analysed to give the axial direct strains and stresses as well as the shear strains as stresses at the sites of the strain gauges. As a result‚ the stress distribution of the beam can be calculated. The aluminium alloy beam was

(in your own words) of the following and give an example of each: A load is a force which are applied to a structure in any direction Support reaction is how much load force there will be needed on a part of the structure to keep the load supported. Ductility when a material is not rigid and can move when loads are applied to them will deflect and stretch without failing. Tensile strength is measured in mega Pascals it is the strength of the materials against failure under pulling of

conducted to understand the behaviour of a simple structure with a rectangular cross-section. The test was completed succesfully although some mistakes occured between theoretical and empirical results. The second experiment consited of an unsymmetrical beam‚ of which the determination of its principal axes was made. Then the third experiment‚ shear centre‚ was conducted in order to find the shear centre. Finally‚ all the experiments were completed‚ and the objectives were met‚ even with the presence of

Hot air oven curing‚ Sunlight curing and ambient curing‚ the 100% FA based GPC produce higher flexural strength of 24.97 N/mm2 under hot air oven curing compare to other 4. On adding 10% PSA into the FA based GPC beam‚ the flexural strength is more or less same among three different curing condition in the following order HAOC >SLC
