Hi all! Im new to the forum, came across it from googling the problem which I had and someone was having difficuilty with a question like this on here! Here's the question I have...

The coefficient of rigidity,n, of a wire of lengthLand uniform diameterdis given by

n=AL/d^4

IfAis a constant and the parametersLanddare known to within ± 2% of their correct values, estimate the maximum possible percentage error in the calculated value ofn.

2. Relevant equations

n=AL/d^4

3. The attempt at a solution

dn = dn/dL x dL + dn/dA x dA

dn = A/d^4 dL + L/d^4 dA

n = A/d^4 x ΔL + L/d^4 x ΔA

n = ΔL/L + ΔA/A

Where do I go from here? Any help will be greatly appreciated :)
