Homework Statement
For my physics course work i need to work out the uncertainty of stress, is there formula for this or is it just the largest value of uncertainty
for example is my area is 7.548E-08 +/- 6.452% and my force 2 +/- 25%
Homework Equations
stress= Force/area
The Attempt at a Solution
I tried putting both the uncertaintys in the equation for stess so 6.452/25% but the uncertainty becomes far to small then
