only (5 marks) b) Calculate the nominal diameter of a deformed (ribbed) high tensile reinforcement steel bar if a specimen of 400mm length weighs 950g. (Hint: The density of steel is 7.85g/cm3 and steel comes with nominal diameters of 8, 10, 12, 14, 16, 18, 20, 25 and 30mm. The permissible deviation in area is 4%) (5 marks) il dronned in hydrous solution, start corroding, and why?
