- @Arjun Siddharth, Please provide the full paper rather than just a small fragment.
- Is equation 17 supposed to be an approximation for equation 16, under certain conditions? If so, then what values of x were used to compute ? And what were the values of , and E, and I, and L? What is the funciton ?
- Equation 17 includes four constants: 2.7E-5, 99, 0.01, and 1.207E-5. Were all of those constants obtained by curve-fitting, or were some of them set in advance, based on other knowledge?
- Equation 17 is for . Does the bar over μ mean it is an average? If so, then an average over what variable, and over what range of values?

@Arjun Siddharth, EI appears as a constant factor in the denominator of eq. 16 for . Therefore if you use a different value of EI than the authors, then multiply by the factor .

For different vaues of L, just plug in L into equation 17.
