Roger cotes modulus and modular ratio

WebIn composite design, the modular ratio, n = Es/Ec, is important. For 3,000 psi, the n-value for normal weight concrete is 9; for lightweight concrete weighing 100 pcf, the n-value is 15; and at 115 pcf, the n-value is 12.In designing with lightweight concrete in composite design, it is recommended that no differentiation be made in n-values for preliminary design only.

(b) Young's modulus of elasticity of concrete to Young's modulus of elasticity of /reinforcement material. WebIn C++, Modulus is performed using arithmetic operator %. Modulus is also called modular division or modulo. The operator takes two operands and returns the reminder after performing division of dividend by divisor.
