Question

In a fillet weld, the direct shear stress and bending tensile stress are 60 MPa and 140 MPa, respectively. As per IS 800 : 2007 the equivalent stress will be MPa.

• A. 174.36

Answer 1

The correct option is A 174.36

$\because f_e=\sqrt{f_t^2+3.q^2}$
$=\sqrt{{140}^2+3\times {60}^2}=174.36\text{MPa}$
$f_e\le \frac{f_u}{\sqrt{3}{\gamma }_m}=\frac{400}{\sqrt{3}\times 1.25}=184.75\text{MPa}$
So equivalent stress = 174.36 MPa
