mm
Enter all values including δmax and click “Calculate h”
Unit Notes:
• Geometric values (B, L, b, δ) are entered in mm but converted to cm for calculation
• Pressure p and modulus E must be in kgf/cm²
• Result h is displayed in mm
• Geometric values (B, L, b, δ) are entered in mm but converted to cm for calculation
• Pressure p and modulus E must be in kgf/cm²
• Result h is displayed in mm
