Does anyone know the spring rate or maximum force that a 2-1/2" Inturra High Tension spring can exert?
Here's what I know. The cross-sectional area of my blade is 0.01469 square inches.
Please check my 50 years from college memory of stress calculations. If you need 15,000 psi to tension the blade properly, then the spring would need to exert somewhere near 220 pounds of force to create that much tension. Since two sides of the blade are in tension that would be 440 pounds total force. Can any 2-1/2" x .730 dia. spring do that? And, can the average 14" band saw handle that much tension?
