JNTUH B.Tech 2nd year Elements of Mechanical Engineering gives you detail Elements of Mechanical Engineering R13 year subject. It will be help full you to understand you complete curriculum of the year.<\/p>\n
Objective<\/strong><\/p>\n To give an insight to students about the behaviour of materials under external forces. The concept of\u00a0stress, strain, elasticity etc. as applied to various structures under loading are included.<\/p>\n UNIT-I<\/strong><\/p>\n Stresses and strains: kinds of \u2013 stress-strains, elasticity and plasticity, Hooks law, stress \u2013strain diagrams,\u00a0modules of elasticity, Poisson\u2019s ratio, linear and volumetric strain, relation between E, N, and K, bars of uniform\u00a0strength, compound bars and temperature stresses.<\/p>\n UNIT-II<\/strong><\/p>\n Types of supports \u2013 loads \u2013 Shear force and bending moment for cantilever and simply supported beams without\u00a0overhanging for all types of loads. Theory of simple bending, simple bending formula, Distribution of Flexural\u00a0and Shear stress in Beam section \u2013 Shear stress formula \u2013 Shear stress distribution for some standard sections.<\/p>\n UNIT-III<\/strong><\/p>\n Thin cylindrical shells: stress in cylindrical shells due to internal pressures, circumferential stress, longitudinal\u00a0stress, design of thin cylindrical shells, spherical shells, change in dimension of the shell due to internal pressure,\u00a0change in volume of the shell due to internal pressure\u00a0Thick Cylinders : Lame\u2019s equation- cylinders subjected to inside and outside pressures Columns and Struts.<\/p>\n
