Pls do not solve the question. My question is how can i determine the the stress axis, for instance sigma(x) or sigma (y)? In the question, the Moment (Mz) is causing the holder's y axis to bend. So the normal stress should be sigma(y) = -P/A + MzY/I instead of what the answer has given sigma(x) = -P/A + MzY/I? sigma (x) should be = 0 instead of signma(y). Am i right?

Pls do not solve the question. My question is how can i determine the the stress axis, for instance sigma(x) or sigma (y)? In the question, the Moment (Mz) is causing the holder's y axis to bend. So shouldnt the normal stress be sigma(y) = -P/A + MzY/I instead of what the answer has given sigma(x) = -P/A + MzY/I. sigma (x) should be = 0 instead of signma(y). am i right?
