Pressure Angles
" Pressure angle affects the force that tends to separate mating gears. High pressure angle decreases the contact ratio but provides a tooth of higher capacity and allows gears to have fewer teeth without undercutting."
By what factor are 20PA gears stronger than 14.5?
Also, what is the formula to calculate the max force on a gear?
