Why is stress not treated as a vector quantity even though force is?
AIt has no unit of measure
BIt is always zero at equilibrium
CIt depends on temperature only
DIt cannot be given one direction
Answer & Solution
Correct answer: D. It cannot be given one direction
Force on one side of a section has a definite direction, but the stress at that section cannot be assigned one direction, so it is not a vector.
