LECTURE -05 BASIC ASSUMPTIONS IN WSM,BASIC ASSUMPTIONS IN THE THEORY OF SIMPLE BENDING OF RCC BEAM.
Assumptions in theory of simple bending (i) The material is homogeneous and isotropic. (ii) Modulus of elasticity is the same in tension and in compression. (iii) Stresses are within the elastic limit. (iv) Plane section remains plane even after deformations. (v) The beam is initially straight and every layer of it is free to expand or contract. (vi) The radius of curvature of bent beam is very large compared to depth of the beam
