OBJECTIVES:
- To introduce various behavior of structural components under various loading conditions.
UNIT I INTRODUCTION 8
Definition of stress, strain and their relations – relations between material constants – axial loading - statically determinate and indeterminate problems in tension & compression – plane truss analysis – method of joints – method of sections – 3-D trusses – thermal stresses – impact loading.
UNIT II STRESSES IN BEAMS 10
Shear force & bending moment diagrams: bending and shear stress variation in beams of symmetric sections, a typical spar section: beams of uniform strength - beams of two materials.
UNIT III DEFLECTION OF BEAMS 10
Double integration method – macaulay’s method – moment area method – conjugate beam method –
principle of superposition – maxwell’s reciprocal theorem.
UNIT IV TORSION – SPRINGS – COLUMNS 10
Torsion of solid and hollow circular shafts – shear stress variation – open and closed-coiled helical springs – stresses in helical springs – classification of columns – euler buckling – columns with different end conditions.
UNIT V BIAXIAL STRESSES 7
Stresses in thin-walled pressure vessels – combined loading of circular shaft with bending, torsion and axial loadings – Mohr’s circle and its construction – determination of principal stresses.
TOTAL: 45 PERIODS
OUTCOMES
- Solve the problems related to the structural components under various loading conditions.
