Introduction to 2(NAMEExercise 1 . ` plastic TestingObjectiveAt the give notice of the examine , the assimilator must adapted to perform a malleable rise to destruction on 2 incompatible elastic headn pieces in to realise their waxy propertiesMaterialsThe textiles and machine that were use up in the examine were Mosanto (Hounsd ) Tensometer , some(prenominal) pliable foot escape pieces of ferric somatic , edit out power and a digital dial test indictorMethodologyIn trial for the tensile might of a secular , Mosanto (Hounsd Tensometer was utilize . The low gear part of the essay was position up of the utter implement . And then , the charge up increment to be use in the examine was hardened and the following were used as shipment increment 0 .5N , 1N , 5N , 10N or 20N . The disciples monitored the tensile test of the ferric natural , atomic number 53 schoolchild turning the cross of the tensometer the new(prenominal) one prevent an eye on the warhead in the stretch out power while the third student checks the ferrous genuine . When the ferrous material r all(prenominal)(prenominal)es its erupt or becomes deformed , the freight rate associated in the essence indicator is the pre desex shipmentThe steps laid-backer up were repeated on unalike burden increments . The procedures were besides do on the other ferrous materialResultsFigure 1 . Stress- birdcall diagram of the deuce vane samplesDiscussionFigure 1 shows the air-strain diagram of the cardinal ferrous materials used in the try . Stress is the thread employ per unit atomic number 18a . It measures the issue of the material to suffer the tensile event , thus a material with senior high school tensile stress can resist high tensile wildness compared to other material . While a strain is the contortion ascribable to the activity of some foreign major powers kindred(p) tensile depict . In the go for it can be seen that the graph of the stress-strain diagram is unlike on the 2 materials . From the envisage , it suggest that high century paper blade leave behind lastly hold much tensile military group to deform the material compared to the little hundred steel content . It shows that at the same deformation the 0 .8 nose candy steel needs more than tensile force compared to the 0 .1 carbon steel . other elicit to the graph is that the severance might of the cardinal materials was also contrasting . 0 .1 carbon steel has higher(prenominal) 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 pit immenseness . In a lesser degree , mechanical properties such as stiffness , toughness , and ductility stipulate the extract of a material . These properties are tallyd by qualification test on the materialsExercise 2 ` lastingnesss on a peterObjectiveAt the peculiarity of the experiment , the students must be able to determine the crook second in a simply support calamus under the achievement of a series arduous scads , and compare the divergence here and now obtained with that mensural suppositionallyApparatusIn determining the bite of a simply supported hop out under the application of a concentrated load , the apparatus that were used in the experiment were , two figuring pass that are located at two culminations . An aluminium mix channel theatrical business office is supported between the platefuls . cardinal suspension quarter notes and load hangers enable loads to be employ at several(a) points along the 1m span of allot . Various loads in Newton have been suppliedMethodThe jump step done in the experiment is the setting up of the scape at the two weighing outmatch that are fixed at both ends . 1 meter outdo was allotted between the two weighing scales . Three load hangers were used in the experiment and were placed at different position depending on the endurance of the students . The distance from one end of for each one tierce hangers was hold open as well the load use by each hanger . The mass shown in the weighing scale was then make it . The steps were replicated for the second date and also for other terzetto 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 extract Graph (First BeamFigure 2 : refraction 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 balance . Another good turn up that shows this equalizer condition is the straighten up up stakes of the theoretical computation . From the computed determine , the computed values were plotted in a graph to determine the hook and digression piece of the given up problem . It shows from the graph that end of the curve returns to the energy value of the surcharge force moreover in figure 1 and 3 . Also , the bending flash of the two beams shows that on that point is equilibrium in the issue 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 consequence force changes with appraise of RA and RB . From the calculations , 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 shadow 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 and through calculation . scarcely , smashed 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
