An A36 Channel compression member of 4.76m length is laterally supported at mid-length on its major axis and at third points on its minor axis. The member has fixed supports at both ends. The properties of the channel section: A=1135mm² , Ix=0.86x10⁶ mm⁴ , Iy=0.13x10⁶ mm⁴ . Calculate the maximum Slenderness Ratio of the member. Express your answer in 2 decimal places.
