Strength of materials by sadhu singh scribd

Theory of simple bending: Stresses due to bending of initially straight beams, theory and assumptions, geometrical characteristics of sections, application of bending formula to simply supported beams of circular, rectangular and I sections, flitched beams. Shearing force and bending moment in beams: Types of loads and supports, various types of beams, inter relation between SF & BM diagrams, shearing force and bending moment diagrams for various types of loading and supports, maximum bending moment and point of contraflexure. Thin walled vessels : Thin cylinders subjected to internal pressure, circumferential and longitudinal stresses and strains, maximum shear stress, increase in diameter and volume of vessel, thin spherical shells subjected to internal pressure, thin cylinders with hemispherical ends, wire winding of thin cylinders. Torsion of circular shafts : Torque and horse-power, angle of twist, shear stresses in hollow and solids shafts within elastic limit, derivation of torsion equation, assumptions, stepped and composite shafts, closed coil helical springs subjected to axial loads and couple. Venant, stress-strain diagrams, principle of superposition, stress and strain in bars subjected to tension and compression, elongation due to self weight, composite sections, thermal stresses, poissonвЂ™s ratio, relation between elastic constants. Simple Stress & Strain: Mechanical properties of solids, concept of stress and strain, normal and shear stresses, HookвЂ™s law, principle of St. Objective: The objective of the paper is to facilitate the student with the basics of Strength of Materials that are required for an engineering student. However, student may be asked to attempt only 1 question from each unit. No.1 rest of the paper shall consist of four units as per the syllabus, every unit should have two questions. This question should have objective or short answer type questions. 1 should be compulsory and cover the entire syllabus.
