I tried looking this up on line but all I could find is annual inflation rate for the past to now. I do not know what this question is called (eg. liner equation, logarithm,radicals etc.) so it is hard to look it up. This question is on a extra credit worksheet (due. tomorrow march22)so we did not resently learn this, I think it is from previous math and I dont remember how to do this.

Question 426518: Engineers use complex mathematical formulas when designing aircrafts. For example, stringers used in the wing of an air plane must be able to support a certain load. Engineers have to use a stringer with the right diameter for the job. Using a smaller size poses a safety hazard. Using a larger size is a waste of material and will result in increased cost to the plane's operator.
Let's assume that the stress S on a rod is given by the formula,
S = (load)/(cross sectional area).
Let's assume that the air plane uses an aluminium rod with diameter 20mm to support a load of 5 x 10^4 Newton. Engineers know that maximum stress on Aluminium is 1 x 10^ 8 Newtons/m^2. How do we determine whether the rod can withstand the load?
