Solution

The correct option is B 104
Effective length of weld = 80 + 70 + 80 = 230 mm
Thickness of throat $= 0.7 \times s = 0.7 \times 6 = 4.2 m m$
$∴$ Safe load $= f \times l \times t$
$= \frac{108}{1000} \times 230 \times 4.2 k N ≃ 104 k N$

Two plates of 8 mm thickness each are connected by a fillet weld of 6 mm thickness as shown in figure below.

The permissible stresses in the plate and the weld are 160 MPa and 120 MPa, respectively. Assuming the length of the weld as shown in the figure to be the effective length, the permissible tensile load P is kN.

A fillet - welded joint is shown in the figure. The size of the weld is 8 mm safe stress in the weld is $120 N / m m^{2}$ . The safe force to which the weld can be subjected will be kN.
