MECHANICS OF SOLIDS

LPTC

3003

OBJECTIVES:
• To understand the fundamental concepts of stress & strain and its deformation under loads.
• To analyze the determinate beams and determine shear force and bending moment.
• To apply the mathematical knowledge to calculate the deformation behavior of beams.
• To understand the effect of torsion on shafts and springs.
• To analyze a complete two dimensional state of stress.

UNIT I

STRESS AND STRAIN

9

Stress and strain at a point – Tension, Compression, Shear Stress – Hooke’s Law –Relationship among elastic constants – Ultimate Stress – Yield Stress – Factor of Safety –Thermal Stresses – strain Energy due to Axial Force – Resilience – Stresses due to impact and Suddenly Applied Load.

UNIT II

SHEAR AND BENDING IN BEAMS

9

Beams and Bending- Types of loads, supports – Shear Force and Bending Moment Diagrams for statically determinate beam – cantilever beam – Simply supported beam - with concentrated load - uniformly distributed load

UNIT III

DEFLECTION OF BEAMS

9

Double integration method - Macaulay's methods - Area moment method - conjugate beam method for computation of slopes and deflections of determinant beams.

UNIT IV

TORSION

9

Torsion of Circular and Hollow Shafts – Stresses and Deflection in Circular Solid and Hollow Shafts – strain energy due to torsion – Power transmitted to shaft – Shaft in series and parallel – Closed and Open Coiled helical springs – Springs in series and parallel.

UNIT V

THIN CYLINDERS AND THEORIES OF FAILURE

9

Thin cylinders – Stresses in thin cylindrical shell due to internal pressure – circumferential and longitudinal stresses - Theories of failure - maximum Principal stress - maximum Principal strain - Shear stress - Total strain energy - Energy distortion theories
