Unformatted text preview: ISTANBUL TECHN ICAL UN IVERSI TY Faculty of Mechanical Engineering MAK 411E Experimental Methods in Engineering “Strength of Materials” Experiment Report Automotive Division 15.03.2010 Adem Canda ş 030050019 T HE PURPOSE OF T HE EXPER I M ENT The purpose of the experiment is to determine the stress values on a thin-walled pressure vessel and compare with theoretical results. T HE T HEORY Strain Gage: Strain gauge is a device that is used to measure strain using the relationship between the electrical resistance and deformation. Calculation (Theoretical): The axial stress component, σ a , can be obtained using the static equilibrium of the side cap: The tangential stress component, σ t , is obtained in a similar way: T HE T HEORET ICAL RESULTS Meas No P(kgf/cm²) σ a MPa (Theo) σ t MPa (Theo) REF 1 10 6.9703 13.9405 2 20 13.9405 27.8811 3 30 20.9108 41.8216 4 40 27.8811 55.7621 5 50 34.8513 69.7026 6 60 41.8216 83.6432 7 70 48.7918 97.5837-1- T HE EXPER I MENT The cylindrical tank, whose dimensions are given below is subjected to an...
