Consider the fillet-welded lap joint shown in the figure (not to scale). The length of the weld shown is the effective length. The welded surfaces meet at right angle. The weld size is 8 mm, and the permissible stress in the weld is 120 MPa. What is the safe load P (in kN, rounded off to one decimal place) that can be transmitted by this welded joint? ___________

A weld is used for joining an angle section ISA 100 mm $$\times$$ 100 mm $$\times$$ 10 mm to a gusset plate of thickness 15 mm to transmit a tensile load. The permissible stress in the angle is 150 MPa and the permissible shear stress on the section through the throat of the fillet weld is 108 MPa. The location of the centroid of the angle is represented by C_yy in the figure, where C_yy = 28.4 mm. The area of cross-section of the angle is 1903 mm². Assuming the effective throat thickness of the weld to be 0.7 times the given weld size, the lengths L₁ and L₂ (rounded off to the nearest integer) of the weld required to transmit a load equal to the full strength of the tension member are, respectively

For the fillet weld of size $$'S'$$ shown in the adjoining figure the effective throat thickness is
