JNTUK B.Tech Elements of Mechanical Engineering gives you detail information of Elements of Mechanical Engineering R13 syllabus It will be help full to understand you complete curriculum of the year.
Learning Objectives: The content of this course shall provide the student the basic concepts of various mechanical systems and exposes the student to a wide range of equipment and their utility in a practical situation. It shall provide the fundamental principles of materials, fuels, Steam, I.C.Engines, compressors, hydraulic machines and transmission systems that usually exist in any process plant.
UNIT –I: Stresses and strains: kinds of – stress-strains, elasticity and plasticity, Hooks law, stress –strain diagrams, modules of elasticity, Poisson’s ratio, linear and volumetric strain, relation between E, N, and K, bars of uniform strength, compound bars and temperature stresses.
UNIT– II: Types of supports – loads – Shear force and bending moment for cantilever and simply supported beams without overhanging for all types of loads. Theory of simple bending, simple bending formula,Distribution of Flexural and Shear stress in Beam section – Shear stress formula – Shear stress distribution for some standard sections
UNIT-III: Thin cylindrical shells: stress in cylindrical shells due to internal pressures, circumferential stress, longitudinal stress, design of thin cylindrical shells, spherical shells, change in dimension of the shell due to internal pressure, change in volume of the shell due to internal pressure. Thick Cylinders: Lame’s equation- cylinders subjected to inside and outside pressures columns and Struts.
UNIT-IV: Steam boilers and Reciprocating air compressors: Classification of boilers, essentialities of boilers, selection of different types of boilers, study of boilers, boiler mountings and accessories. Reciprocating air compressors: uses of compressed air, work done in single stage and two-stage compression, inter cooling and simple problems.
UNIT-V: Internal combustion engines: classification of IC engines, basic engine components and nomenclature, working principle of engines, Four strokes and two stroke petrol and diesel engines, comparison of CI and SI engines, comparison of four stroke and two stroke engines, simple problems such as indicated power, brake power, friction power, specific fuel consumption, brake thermal efficiency, indicated thermal efficiency and mechanical efficiency.
UNIT-VI: Transmission systems: Belts –Ropes and chain: belt and rope drives, velocity ratio, slip, length of belt , open belt and cross belt drives, ratio of friction tensions, centrifugal tension in a belt, power transmitted by belts and ropes, initial tensions in the belt, simple problems. Gear trains: classification of gears, gear trains velocity ratio, simple, compound –reverted and
epicyclic gear trains.
