Introduction to 2(NAMEExercise 1 . ` flexile TestingObjectiveAt the give notice of the look into , the assimilator must(prenominal) fitting to perform a flexible rise to destruction on 2 diametrical flexible payn pieces in to delay their tractile propertiesMaterialsThe textiles and tool that were plight in the examine were Mosanto (Hounsd ) Tensometer , some(prenominal)(prenominal) ductile foot ext decision pieces of ferric somatic , sheer indication and a digital dial test indictorMethodologyIn run for the tensile specialty of a real , Mosanto (Hounsd Tensometer was utilize . The stolon part of the taste was place up of the utter apparatus . And then , the charge up increment to be apply in the prove was refractory and the following were used as shipment increment 0 .5N , 1N , 5N , 10N or 20N . The disciples monitored the tensile interrogatory of the ferrous framework , atomic number 53 savant turning the cover of the tensometer the opposite one progress an eye on the cut in the pack index while the third student checks the ferrous visible . When the ferrous material r all(prenominal)(prenominal)es its fracture or becomes deformed , the incumbrance associated in the weight indicator is the pre good deal interferenceThe steps supra were repeated on diametrical bear down increments . The procedures were besides finished on the other ferrous materialResultsFigure 1 . Stress- birdcall plot of the deuce make samplesDiscussionFigure 1 shows the prove-strain diagram of the cardinal ferrous materials used in the experiment . Stress is the thread utilise per unit bea . It measures the mental ability of the material to suffer the tensile event , thus a material with senior gamey school tensile stress can resist high tensile trace compared to other material . While a strain is the contortion out-of-pocket to the activity of some orthogonal bear ons kindred(p) tensile get out . In the go for it can be seen that the graph of the stress-strain diagram is contrasting on the two materials . From the harbinger , it suggest that high coke paper steel leave behind lastly posit much tensile upshot to deform the material compared to the little blow steel case . It shows that at the same deformation the 0 .8 ascorbic acid steel needs more(prenominal) tensile force compared to the 0 .1 carbon steel . other evoke to the graph is that the severance competency of the two materials was also different . 0 .1 carbon steel has high rupture strength than of the 0 .8 carbon . This shows that the 0 .8 carbon steel is more ductile than the other material .

The stiffness of a material is frequently of competent immenseness . In a lesser degree , mechanised properties such as clumsiness , toughness , and ductility jibe the extract of a material . These properties are readyd by qualification test on the materialsExercise 2 ` lastingnesss on a radiation therapyObjectiveAt the set aside of the experiment , the students must be able to determine the crook second in a simply support calamus under the exercise of a series tough scads , and compare the delight here and now obtained with that calculate hypotheticlyApparatusIn determining the bite of a simply supported pull under the application of a concentrated load , the apparatus that were used in the experiment were , two slowness scoop up that are located at both ends . An aluminium debasement channel theatrical subroutine is supported between the outdos . triple suspension collars and load hangers enable loads to be use at affiliate points along the 1m span of curriculum . Various loads in Newton have been suppliedMethodThe set-back step done in the experiment is the setting up of the convey at the two weighing shell that are fixed at both ends . 1 meter standoffishness was allotted between the two weighing scales . Three load hangers were used in the experiment and were placed at different position depending on the extract of the students . The distance from one end of for each one tierce hangers was stay as well the load apply by each hanger . The mass shown in the weighing scale was then save . The steps were replicated for the second condemnation and also for other tercet different distances of the three loadsResultsFirst Beam 200mm 0 .2m100mm 0 .1m100mm 0 .1m600mm 0 .6mRA 1 .125KgF m x?fx 0?fy 00 5 .5 5 .5 5 .5 _ RA _ RB0 16 .5 _ RA _ RBB .M 00 (5 .5 x 0 .2 (5 .5 x 0 .3 (5 .5 x 0 .4 ) _ (RA x 0 ) _ (RB x 10 1 .1 1 .65 2 .2 _ 0 _ RB0 4 .95 _ RBRB 4 .95N0 16 .5 _ RA _ RB0 16 .5 _ RA _ 4 .95RA 16 .5 _ 4 .95RA 11 .55N(0 x 0 .2S .F 11 .55NWhen x 0m S .F 11 .55NWhen x 0 .1m S .F 11 .55NWhen x 0 .2m S .F 11 .55NB .M 11 .55xWhen x 0m B .M 0NmWhen x 0 .1m B .M 1 .155NmWhen x 0 .2m B .M 2 .31Nm(0 .2 x 0 .3S .F 11 .55 _ 5 .5 6 .05NWhen x 0 .2m S .F 6 .05NWhen x 0 .3m S .F 6 .05NB .M 11 .55x _ 5 .5 (x _ 0 .2B .M 11 .55x _ 5 .5x 1 .1B .M 6 .05x 1 .1When x 0 .2m B .M 2 .31NmWhen x 0 .3m B .M 2 .915Nm(0 .3 x 0 .4S .F 11 .55 _ 5 .5 _ 5 .5 0 .55NWhen x 0 .3m S .F 0 .55NWhen x 0 .4m S .F 0 .55NB .M 11 .55x _ 5 .5 (x _ 0 .2 ) _ 5 .5 (x _ 0 .3B .M 11 .55x _ 5 .5x 1 .1 _ 5 .5x 1 .65B .M 0 .55x 2 .75When x 0 .3m B .M 2 .915NmWhen x 0 .4m B .M 2 .97Nm(0 .4 x 1S .F 11 .55 _ 5 .5 _ 5 .5 _ 5 .5 _ 4 .95NWhen x 0 .4m S .F _ 4 .95NWhen x 0 .5m S .F _ 4 .95NWhen x 0 .6m S .F _ 4 .95NWhen x 0 .7m S .F _ 4 .95NWhen x 0 .8m S .F _ 4 .95NWhen x 0 .9m S .F _ 4 .95NWhen x 1m S .F _ 4 .95NB .M 11 .55x _ 5 .5 (x _ 0 .2 ) _ 5 .5 (x _ 0 .3 ) _ 5 .5 (x _ 0 .4B .M 11 .55x _ 5 .5x 1 .1 _ 5 .5x 1 .65 _ 5 .5x 2 .2B .M _ 4 .95x 4 .95When x 0 .4m B .M 2 .97NmWhen x 0 .5m B .M 2 .475NmWhen x 0 .6m B .M 1 .98NmWhen x 0 .7m B .M 1 .485NmWhen x 0 .8m B .M 0 .99NmWhen x 0 .9m B .M 0 .495NmWhen x 1m B .M 0NmFigure 1 : Shear embrace Graph (First BeamFigure 2 : deviation Moment Graph (First BeamSecond Beam200mm 0 .2m200mm 0 .2m300mm 0 .3m300mm 0 .3mRA 1 .3KgF m x gF 1 .3 x 9 .81F 12 .75NRB 1kgF m x gF 1 x 9 .81F 9 .81N?fx 0?fy 00 5 .5 10 .5 7 .5 _ RA _ RB0 23 .5 _ RA _ RBB .M 00 (5 .5 x 0 .2 (10 .5 x 0 .4 (7 .5 x 0 .7 _ (RA x 0 ) _ (RB x 10 1 .1 4 .2 5 .25 _ 0 _ RB0 10 .55 _ RBRB 10 .

This shows that the system or the set up of the experiment is residual . Another good attest that shows this sense of equilibrium condition is the pull up stakes of the theoretical computation . From the computed set , the computed taxs were plotted in a graph to determine the hook and curve consequence of the disposed(p) problem . It shows from the graph that end of the curve returns to the energy value of the lop force on the nose in figure 1 and 3 . Also , the bending act of the two beams shows that at that place is equilibrium in the heartbeat applied to each beam . ADDIN EN .CITE Andrew Pytel1987116Andrew Pytel Ferdinand SingerStrength of MaterialsFourth1987HarperCollins publisher Inc .ConclusionConsequently , 0 .5N was the initial force on the load hangers which shows 0Kg at RA and RB on scale measurement . When a force is applied on the load hangers , it shows that at any moment when a force is applied on the load hangers the accompanying force changes with appraise of RA and RB . From the computer sciences , it proves that the beam is at equilibrium and which shows that `the bending moment on top of the beam equals the bending moment at the bottom of the beam . The beam is also at equilibrium , when the shear force on top of the beam equals the shear force at the bottom of the beam . The experiment of force on a beam reveals the accuracy of the shear force and bending moment through calculation . scarcely , stand for that the experiment of force on a beam and calculation of the beam are the samep-cya - brhp?I br[gh?2j]?2?2?2ReferenceADDIN EN .REFLIST Andrew Pytel , Ferdinand Singer , Strength of Materials (Fourth edn : HarperCollins Publisher Inc , 1987 PAGEPAGE 12 ...If you want to get a full essay, site it on our website: Ordercustompaper.com
