OBJECTIVES:

  • To learn the fundamental concepts of Stress, Strain and deformation of solids.
  • To know the mechanism of load transfer in beams, the induced stress resultants and
    deformations.
  • To understand the effect of torsion on shafts and springs.

between intensity of load, Shear Force and Bending moment – Shear Force and Bending Moment
Diagrams for Cantilever, simply supported and overhanging beams with concentrated load,
uniformly distributed load, uniformly varying load and concentrated moment. Theory of Simple
Bending – Stress Distribution due to bending moment and shearing force – Flitched Beams – Leaf
Springs.

UNIT III DEFLECTION OF BEAMS 9
