ME 215 MATERIALS LABORATORYTEST_1TENSILE TEST1. Read the theory of tensile behaviour of materials in your notes.2. Repeat the following procedure for testing each specimen:(a) Measure and note the gauge length and gauge diameter of the specimen(b) Set the direct measurement tools for theelongation and reduction in diameter forthis specimen.(c) Set the tensile testing machine!i. Select the ma"imum load and assemble the spring and scale for this ma"imumload.ii. #ssemble specimen and chuc$s.iii. %osition the graph paper.iv. &hec$ the magnification ratio.v. 'urn the handle until the specimen (ust tightens. )o not apply too much loadwhile doing this.vi. #d(ust the mercury level to *ero load.(d) Start thetestingprocedureslowlyandgraduallyincreasetheloaduntil specimenfractures.(e) +sing the direct mesuring tools! read theelongation andreduction in diameter ofthe fractured specimen and note these values.(f) Measure and note the gauge length and diameter of the nec$ed region of the fracturedspecimen. (g) +sing the measurements ta$en in step (a)! calculate theelongation andreductionin diameter.(h) 'hen!i. &ompare the measurement in (e) and (g) for each specimen. ii. &onstruct a stress versus strain and true stress versus true strain diagram byusing the load,e"tension diagram.iii. &alculatetheyieldstrengthandultimatetensilestrength(useoff,set yieldstrength if necessary).iv. &alculate:a. -oung.s modulus of elasticity.b.
