Simple Stresses and Strains
CHAPTER OBJECTIVES
In this chapter, we will learn about:
- Various types of (a) stresses as tensile and compressive stresses, positive and negative shear stresses, complementary shear stresses, volumetric stress; (b) strains as longitudinal strain, lateral strain, shear strain; and (c) strain energy absorbed by a body during deformation.
- Difference between gradual, sudden and impact loads.
- Elastic constants of a material as Young’s modulus, Bulk modulus, Shear modulus, Poisson’s ratio as deformation in a body depend on these elastic constants.
- Stresses developed in a bar due to its own weight.
- Bar of uniform strength in which stress due to self-weight remains constant.
- Variation of stress in a stepped bar, uniformly ...
