Summary:: How to combine two formulas to find the material index
Attached is the problem I am having trouble understanding.
I have been able to do the first two combinations by transposing for A in the mass equation then subsituting into the stress equation. The next combinations (in red box) are harder to see. Is L isolated and then inserted into the next formula? How is this broken down?
Thanks for any help on this.
