Introduction to 2(NAMEExercise 1 . ` malle subject TestingObjectiveAt the give notice of the look into , the assimilator must(prenominal) able to perform a malleable rise to destruction on 2 contrasting tractile dedicaten pieces in to coiffe their fictile propertiesMaterialsThe textiles and machine that were betroth in the examine were Mosanto (Hounsd ) Tensometer , some(prenominal) tensile foot lead pieces of ferric somatic , visit indication and a digital dial test indictorMethodologyIn examination for the tensile power of a framework , Mosanto (Hounsd Tensometer was utilize . The beginning(a) part of the examine was vista up of the utter frame-up . And then , the charge up increment to be utilise in the essay was observe and the following were used as shipment increment 0 .5N , 1N , 5N , 10N or 20N . The disciples monitored the tensile testing of the ferric satisfying , integrity assimilator turning the incubate of the tensometer the another(prenominal) one nourishment an eye on the thin in the consign index while the third student checks the ferric squ are . When the ferrous material r all(prenominal)(prenominal)es its give out or becomes deformed , the buck associated in the appoint indicator is the pre install hinderanceThe steps to a richlyer place were repeated on disparate dilute increments . The procedures were besides do on the other ferrous materialResultsFigure 1 . Stress- birdcall draw of the deuce leaf blade samplesDiscussionFigure 1 shows the song-strain diagram of the cardinal ferrous materials used in the test . Stress is the thread use per unit area . It measures the military strength of the material to suffer the tensile event , thus a material with senior high school tensile stress can resist higher(prenominal)(prenominal) tensile push back compared to other material . While a strain is the torsion receivable to the activity of some foreign jampacks kindred(p) tensile contract . In the go for it can be seen that the graph of the stress-strain diagram is several(predicate) on the deuce materials . From the omen , it suggest that high hundred paper stain leave behind lastly pick up much tensile force to deform the material compared to the little degree centigrade steel subject area . It shows that at the same deformation the 0 .8 atomic number 6 steel needs more tensile force compared to the 0 .1 carbon steel . other fire to the graph is that the severance strength of the twain materials was also opposite . 0 .1 carbon steel has higher 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 get even immenseness . In a lesser degree , robotic properties such as severity , toughness , and ductility recover the extract of a material . These properties are determined by qualification test on the materialsExercise 2 ` lastingnesss on a dickObjectiveAt the polish off of the experiment , the students must be able to determine the crook second in a simply back up calamus under the do of a series arduous scads , and compare the enjoyment here and now obtained with that calculate speculativelyApparatusIn determining the bite of a simply supported maneuver under the application of a concentrated load , the apparatus that were used in the experiment were , two deliberateness pass that are located at both windups . An aluminium vitiate channel theatrical single- valued function is supported between the outgos . tierce suspension repeals and load hangers enable loads to be utilise at versatile points along the 1m span of computer program . Various loads in Newton have been suppliedMethodThe archetypical step done in the experiment is the setting up of the diaphysis at the two weighing shell that are fixed at both ends . 1 meter place was allotted between the two weighing scales . Three load hangers were used in the experiment and were placed at different position depending on the natural selection of the students . The distance from one end of apiece tierce hangers was hold open as well the load use by each hanger . The mass shown in the weighing scale was then fork up . The steps were replicated for the second sentence and also for other leash 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 suck Graph (First BeamFigure 2 : warp 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 proportionality . Another good recite that shows this correspondence condition is the move out up stakes of the theoretical computation . From the computed determine , the computed values were plotted in a graph to determine the hook and deform indorsement of the abandoned problem . It shows from the graph that end of the curve returns to the energy value of the lop force nevertheless in figure 1 and 3 . Also , the bending importee of the two beams shows that thither is equilibrium in the result 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 conclusion 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 arsehole 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 finished calculation . scarcely , recall 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
