Two plates are connected by fillet welds of size $$10$$ $$mm$$ and subjected to tension, as shown in the sketch. The thickness of each plate is $$12$$ $$mm.$$ The yield stress and the ultimate tensile stress of steel are $$250$$ $$MPa$$ and $$410$$ $$MPa,$$ respectively. The welding is done in the workshop $$\left( {{\gamma _{mw}} = 1.25} \right).$$

As per the Limit State Method of $$IS$$ $$800:2007,$$ the minimum length (rounded off to the nearest higher multiple of $$5$$ $$mm$$) of each weld to transmit a force $$P$$ equal to $$270$$ $$kN$$ (factored) is

Two plates, subjected to direct tension, each of $$10$$ $$mm$$ thickness and having widths of $$100$$ $$mm$$ and $$175$$ $$mm,$$ respectively are to be fillet welded with an overlap of $$200$$ $$mm.$$ Given that the permissible weld stress is $$110$$ $$MPa$$ and the permissible stress in steel is $$150$$ $$MPa,$$ then length of the weld required using the maximum permissible weld size as per $$IS:$$ $$800$$ -$$1984$$ is

A fillet-welded joint of $$6$$ $$mm$$ size is shown in the figure. The welded surfaces meet at $$60$$ - $$90$$ degree and permissible stress in the fillet weld is $$108$$ $$MPa.$$ The safe load that can be transmitted by the joint is

$$ISA$$ $$100 \times 100 \times 10mm$$ (cross sectional area $$ = 1903\,\,m{m^2}$$) is welded along $$A$$ and $$B$$ (Refer to figure in the below question) such that the lengths of the weld along $$A$$ and $$B$$ are $${l_1}$$ and $${l_2}$$ respectively. Which of the following is a possibly acceptable combination of $${l_1}$$ and $${l_2}$$
