A 25-tooth steel spur pinion rotates at 600 rpm and transmits 40 kW to a 100- tooth cast-iron gear. The gears have a 25° pressure angle, a face width of 120 mm, and a module of 10 mm. Using an application factor of unity, a size factor of 1.2, a load- distribution factor of 1.5, and a quality level of 7. Find the factor of safety of both gears based on the AGMA bending equations.
