1.	When fillet welds are subjected to combination of normal and shear stress, the equivalent stress is given by :(a) √(fa^2+q^2)(b) √(fa^2+2q^2)(c) √(3fa^2+q^2)(d) √(fa^2+3q^2)I had been asked this question during an online interview.I'm obligated to ask this question of Design of Welds in section Welded Connections of Design of Steel Structures
Answer» The correct answer is (d) √(fa^2+3q^2) The EXPLANATION: When fillet welds are SUBJECTED to combination of normal and shear stress, the equivalent stress is given by fe = √(fa2+3q^2), where fa = normal STRESSES, compression or tension, due to axial force or bending MOMENT, q = shear stress due to shear force or tension.
