Slope deflection method

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 = 1.76E+10 Mpa.mm4 when calculated using

conditions we realise that: c2=0 Using the second set of condition we realise that: c1=ml2EI Subbing these into the full equation, we get: Δ=-mx22EI+mlx2EI Finally, we want to measure the deflection at a point where it is a maximum. Because this is a symmetrically loaded beam, the point where max deflection occurs is at the centre, where x=l/2. Subbing this into the equation we get: Δ=-ml28EI+ml24EI When calculating the experimental axial stress, we used the formula: σaxial=E1-ν2×εax+ν.εtr

INTRODUCTION: The study of large deflection of cantilever beam comes from theory of elasticity. Theory of elasticity state that “solid material will deform under the application of an external force it will again regain their original position when external force is removed is referred to as elasticity”. We took beam made of nickel titanium alloy which regain their original shape after removing external force act on the beam. It’s a prismatic circular cross section

experiment was to study the behaviour 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

INTRODUCTION Archie Unleashed is an attempt to put the basic log analysis methodology for computing water saturation into a readable reference document. The beginning log analyst or petrophysicist should have little difficulty with the terms and concepts utilized in this paper, however, most terms are redefined in appendix A. The basic outline of this document closely follows a previous work written for the casual interpeter in log analysis. Archie Unleashed is meant to carry that work one step

An Introduction to Sensors and Instrumentation Chapter 1 Introduction to Sensors and Transducers Instrumentation is defined as the art and science of measurement and control which is considered as working with instruments used to measure, record, and control process variables (for examples, fluid level and flow, temperature, and pressure). Control and measurement systems are very widely used in the petroleum product (oil and gas) industries, chemical and fertilizer industry, the pulp and paper industry

include the effects of the plasticity index of the clay, Ip, which is shown to have an especially large impact on the correlations when Ip 25%. In practical design, it is recommended that both methods be used and design values be selected for the ultimate shaft friction that represents an average for the two methods. Pile diameter, length, or stiffness or whether the pile is open or closed-ended seem to have little impact on the shaft friction. However, a moderate effect of pile length or flexibility

maintenance. It is can be defined as upgrading or strengthening the bridge structural quality to enhance the performance of the bridge. Strengthening and retrofit methods are different from the repairing and it includes a component host. Most bridges are in need for the retrofit and strengthening every 15 years. There are a lot of strengthening methods like steel pre-stressed girders, micro piles, pile caps, extended footings, abutment wall, wall piers and column bent pier. Other than that, there are also
