This is defined as the length of the scale for a unit value of the functional variable.(a) Functional modulus(b) Young’s modulus(c) Modulus of elasticity(d) Constant modulusI had been asked this question by my school teacher while I was bunking the class.This is a very interesting question from Nomography in portion Nomography, Computer Aided Drafting & Procedure of Estimating of Civil Engineering Drawing

Answer» CORRECT CHOICE is (a) Functional modulus

For explanation I would say: Mathematically, we can write as

m = L/(f(xmax)-f(xmin), where m is the functional modulus

L = SCALE length

xmax and xmin represent the value of the variable x corresponding to the MAXIMUM and minimum values of the function respectively.
