For thin$-$walled approximation, determine the shear flow and shear stress for

given C$-$ section ABCDE having thickness $,$ if the only transverse shear force will

be $$ along y$-$axis in upward direction. In addition to this, determine the location

of shear centre from web $($eccentricity e$)$ for given C$-$section, if d$=30$ cm$,$ b$=20$cm$,$

t$=2$mm$,$ and $=1000$ N in upward direction.
