Question

A strut in a steel truss is composed of two equal angles $$ISA$$ $$150mm 	imes 150mm$$ of thickness $$100$$ $$mm$$ connected back-to back to the same side of a gusset plate. The cross sectional area of each angle is $$2921$$ $$m{m^2}$$ and moment of inertia $$\left( {{{m I}_{XX}} = {{m I}_{YY}}} ight)$$ is $$6335000$$ $$m{m^4}.$$ The distance of the centroid of the angle from its surface $$\left( {{C_x} = {C_y}} ight)$$ is $$40.8$$ $$mm.$$ The minimum radius of gyration of the strut is
