I am searching here question paper for Cochin University B.Tech in Mechanical Engineering5th SemAdvanced Mechanics of Solids Examination in PDF file format? Here I am giving you question paper for Cochin University B.Tech in Mechanical Engineering5th SemAdvanced Mechanics of Solids Examination in PDF file attached with it . Derive straindisplacement relations and compatibility equations for a two dimensional condition. Explain about plain stress and plain strain with the help of examples. OR Derive differential equations of equilibrium for two dimensions. Wing the testing of an automobile using a 60' delta rosette, the following observations were made. (i) ~ , = 2 8 0 x 1 0 ~ , ~ = 1 6 0 x 1 0 ~ , E , =  ~ o x ~ o ~ Find the principal strains and maximum shear strain> Derive an expression for strain components in polar coordinates. A thick cylinder of internal diameter lOOmm and external diameter 200mm is subjected to an internal pressure of 10~/&. Find the variation of radial stress and circumferential stress across wall thickness. OR Derive an expression for radial and tangential slresses developed in a disk of uniform thickness with inner radius 'a' and outer radius 'b' rotating with anaogular velocity w. A steel tube of 300mm outer diameter is to be sluunk on another steel tube of 90mm internal diameter. After shrinking the diameter of the junction is 180mm. Before shrinking the difference in the diameter of the junction is 0.12mm. Determine (i) Shrinkage pressure at interface (ii) Temperature difference to makethe assembly. Take E=200GPa, v2.3, a = l 0 ~ 1 0 " ~ e r ' ~ . Derive Cauchy's stress formulae and hence explain about stress ellipsoid. Derive the cubical equation for determining principal stresses in a three dimensional problem. OR The state of stress at a point is given as Find the principal stresses and principal axes.
