Roger cotes modulus and modular ratio
http://mathforcollege.com/nm/anecdotes/cotes.html WebA modulus function is a function which gives the absolute value of a number or variable. It produces the magnitude of the number of variables. It is also termed as an absolute value function. The outcome of this function is always positive, no matter what input has been given to the function. It is represented as y = x .

WebThe contributions are not just straight addition, but vector contributions, the angle between the complex modulus and the storage modulus is known as the ‘phase angle’. If it’s close to zero it means that most of the overall complex modulus is due to an elastic contribution. This is just a clever way of saying that the product is more of ... WebHowever, concrete has varying moduli, as it is not a perfectly elastic material. Therefore, its short-term modulus \(\left( {{E_s} = 5000\sqrt {{f_{ck}}} } \right)\) is not considered and the long-term modulus of elasticity is considered to take into account the effect of creep and shrinkage. ∴ The modular ratio is taken as

WebThe dynamic modular ratio value used in checks (both individual beam and Floor Vibration) is controlled by the beam property setting labelled “Factor for increased dynamic stiffness of the concrete flange”* (see picture below). WebTranscribed Image Text: Q.14 In the context of elastic theory of reinforced concrete, the modular ratio is defined as the ratio of (a) Young's módulus of elasticity of reinforcement material to Young's modulus of elasticity of concrete. (b) Young's modulus of elasticity of concrete to Young's modulus of elasticity of /reinforcement material.
