EXPERIMENT 2 – BUCKLING OF STRUTS Aim We can find two failure points in members exposed to axial compressive forces‚ also called struts. The first one is squashing of the member‚ which will only happened if a member is “Stocky”. The second‚ and most common one‚ is buckling of the member. This failure happens without much warning‚ and therefore it is important for engineers to be able to calculate what load on structural element will cause buckling. In this experiment‚ we will observe the failure

Experiment 1 : Strut Buckling Introduction: Objective: • To determine the buckling load for a pinned ended strut. Theory: • The critical buckling load‚ Pcr‚ for a pinned ended strut is given by; Pcr = п² EI / (L²) [pic] Apparatus: 1. Vernier Caliper 2. Specimen 3. Steel Ruler 4. Allen Keys 5. Digital indicator [pic] Procedure: 1. Switch on the digital indictor and warm it up for at least 10 minutes. 2. Choose a specimen and measure its length. The width and

Task 1 Foundry Work Sand casting involves many sequences and there are as follows: - Design and manufacturing the casting. When doing this all vertical edges must be tapered as to make it easier to lift the pattern out of the mould. - Contraction allowances have to be added to the pattern because it shrinks in size in all dimensions. In this case it’s Aluminium‚ which has a contraction allowance of 1.3%. - Machining allowance: Castings are usually machined so that they fit perfectly with

39-43 SCIENCES EXPERIMENTAL INVESTIGATION OF THE PHENOMENON OF BUCKLING FOR STEEL AND ALUMINIUM STRUTS Durmuş TÜRKMEN University of Pamukkale‚ Engineering Faculty‚ Denizli -TURKEY ABSTRACT The experiment was carried out to investigate the phenomenon of buckling using simple struts. These results were then compared with the theoretical predictions. Three steel struts of different length were used in the experiment; one of them had fix/pinned-end all the others had pin/pin-end joint

Types of Buckling Engineering is one discipline that is based on several different phenomenon and concepts. Each concept in engineering is as important as other and they all work together to give rise to some new techniques. One phenomenon that is extremely beneficial and widely used in engineering and science is buckling. Buckling is nothing but a phenomenon of mathematical instability‚ which leads to a special failure mode. When a system in equilibrium is subjected to additional load‚ it buckles

load vs the slenderness ratio was used to display several results obtain from the experiment. Introduction The general aim of this experiment was to find whether the short‚ intermediate‚ and long column buckle when the critical load is reached. Various lengths of wooden columns are selected and are subjected to an axial compressive load to a point where the beams either buckle or get crushed. This experiment also tries to find a way to find a range of values for length to decide where the
