The shaft shown in the figure is receiving 10 kW through the gear (3) and is delivering it through a gear (4), turning at 900 RPM. Both gears are helical, they produce equal and opposite axial forces so that their resultant is zero and the bearings would absorb only radial loads in this case. The material of the shaft is drawn and annealed steel with Sy - 36 kpsi, Sut - 52 kpsi, with a turned surface. Both gears are keyed (keys, keyways) to shaft with force fit, corner rounding (notch radius) is 1/16 in. radius. Calculate the safety factor of the tree according to the Soderberg criterion for a probability of failure of 0.1%.
