A $$12$$ $$mm$$ bracket plate is connected to a column flange as shown in the figure below. The bracket transmits a load of $$W = 200\,\,kN$$ to the column flange. $$A$$ $$10$$ $$mm$$ fillet weld is provided along $$AB,$$ $$BC$$ and $$CD.$$ If $$e=350$$ $$mm,$$ $$b=200$$ $$mm$$ and $$d=600$$ $$mm,$$ Verify if the size of the weld provided is adequate. Allowable shearing stress in the fillet weld can be taken to be $$108$$ $$MPa.$$

The stress-strain diagram for two materials A and B is shown below: The following statements are made based on this diagram:
I. Material A is more brittle than material B.
II. The ultimate strength of material B is more than that of A.
With reference to the above statements, which of the following applies?

Pick the incorrect statement from the following four statements:

A frame $$ABCD$$ is supported by a roller at $$A$$ and is on a hinge at $$C$$ as shown below:

The reaction at the roller end $$A$$ is given by
