An overhang hollow shaft having inside diameter 0.5 time outside diameter, carries a cast iron pulley having 800N weights and 900mm diameter, at 250mm from the nearest bearing. The pulley is driven by another pulley mounted on the shaft placed bellow it, to transmit 35kW at 400r.p.m. The belt ends are vertical and parallel; if the ratio of tensions in belt is 3 and the permissible shear stress for material of shaft is limited to 200MPa, determine the diameters of shaft.
