Question

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 modulus

I 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 1

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.
