AI3403 Strength of Materials for Agricultural Engineering Syllabus – Anna University Regulation 2021

COURSE OBJECTIVES:

 To understand the stresses developed in bars, compound, bars, beams, shafts, cylinders and spheres.

UNIT I STRESS, STRAIN AND DEFORMATION OF SOLIDS

Rigid bodies and deformable solids – Tension, Compression and Shear Stresses – Deformation of simple and compound bars – Thermal stresses – Elastic constants – Volumetric strains – Thin shells – circumferential and longitudinal stresses in thin cylinders – deformation of thin cylinder – stresses in spherical shells – Deformation of spherical shells.

UNIT II ANALYSIS OF PLANE TRUSSES

Determinate and indeterminate plane trusses – determination of member forces by method of joints, method of sections and method of tension coefficient.

UNIT III TRANSVERSE LOADING AND STRESSES IN BEAM

Beams – types transverse loading on beams – Shear force and bending moment in beams – Cantilevers – Simply supported beams and over-hanging beams. Theory of simple bending– bending stress distribution – Shear stress distribution – Flitched beams – carriage springs.

UNIT IV TORSION

Torsion formula – stresses and deformation in circular and hollows shafts – Stepped shafts– Deflection in shafts fixed at the both ends – Stresses in helical springs – Deflection of helical springs – carriage springs.

UNIT V DEFLECTION OF BEAMS

Computation of slopes and deflections in determinate beams – Double Integration method – Macaulay‟s method – Area moment method – Conjugate beam method.
