I had a discussion with a friend regarding helical cut gears and straight cut gears. He thinks straight cut gears are stronger and i think helical cut gears are stronger. I have nothing to reinforce my point and neither does he. i know about helical cut gears being quieter and costing more but does anyone know or can guide me to somewhere that shows which style gear is stronger. thanks

Straight cut are stronger because they spread the force over the entire face of the teeth instead of just a small part of the tooth. However, they are quite a bit louder and harder to engage smoothly.
