p sa 15. A straight bevel gear pair has the following data: 50; P¿ 10; and 20° pressure angle. If the gear pair is transmitting 3.5 hp, compute the fore- es on both the pinion and the gear. The pinion speed is 1250 rpm. The face width is 0.70 in. Compute the bend- ing stress and the contact stress for the teeth, and specify a suitable material and heat treatment. The gears are driven by a gasoline engine, and the load is a conveyor provid- ing moderate shock. Assume that neither gear is straddle nounted. N₂ No = 25; No J (M
