Bearing Resistance Calculations
| Pad Properties | |
|---|---|
| X Axis Distance to Edge | x = L / 2 + Ex = 1000 mm |
| Y Axis Distance to Edge | y = W / 2 + Ey = 1000 mm |
| Pad Effective Length | Leff = min(d, L / 2 + Offx - Lbp) + min(d, L / 2 - Offx - Lbp) = 2000 mm |
| Pad Effective Width | Weff = min(d, W / 2 + Offy - Wbp) + min(d, W / 2 - Offy - Wbp) = 2000 mm |
