A mild steel I-section beam of length, I m is loaded as a horizontal cantilever beam. The vertical downward load at the free end varies between 70 KN and 150 KN. Suggest a suitable thickness t of the flange and the web, if the web and flange thicknesses are the same and the depth and width of the I-section are also the same and equal to 10 times the thickness t. Use a factor of safety of 2.2. The suggested life of the rod is 2×10^5 cycles only. Take a surface finish factor of 0.8. Choose the other factors suitably.
