Strain gauge? Answered
i need some help in this homework.
Foil length of strain gauge is L
Resistance of strain gauge is R
Equation is deltaR/R=0.485(deltaL/L)
the strain gauge is given a strain of X%.
The question says to calculate the change in resistance on the strain gauge.
My problem is that i don't understand the X% strain. I'm not asking for answer, just want to know what the X% strain means
