Ultitmate Tensile Strength(psi):

You can enter your own Ultimate Tensile Strength.
(Safe stress can be taken as 1/3 of the ultimate strength.)
See the following websites for ultimate strength values:
matmatch.com

Results:

Load in lbs @ pitch line
Safe static stress per sq. inch of material (lbs/sq. inch)
*Velocity (feet per minute)
Horsepower
Torque (inch lbs)
Gear OD
Gear PD
Service Factor (from load & duration)
*Special Considerations need to be taken if the Pitch Line VELOCITY exceeds: 1200 FPM for Metallic Spur Gears Or 2400 FPM for Helical Gears or Nonmetallic Spur gears
