f spur gears is to be designed for a compressor operating at 300 rpm, driven by a 9 kW, 1200 rpm motor. Centre distance between the axes of gears shafts is 250 mm. Starting torque of the motor taken as 40% extra on the rated torque. Both pinion and gear are made of steel with out=750 Teeth are of 20° pressure angle full-depth involute. If factor of safety is 2, specify dimensions of
