9 The reinforced concrete beam shown is subjected to a positive bending moment of . Knowing that the modulus of elasticity is for the concrete and for the steel, determine the stress in the steel, (b) the maximum stress in the concrete. Fig. P4.49 (a) . (b) .
Expert Answer
Given,Bending Moment, M = 175kN.mModulus of Elasticity of concrete =25GpaModulus of Elasticity of steel =200GpaFrom the Diagram,b=300mmdiameter =25mmd
