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.
