| 6 m lengths | 1 | 5 | 10 | 25 | 50 | 100 |
|---|---|---|---|---|---|---|
| Weight | 16.18 kg | 80.91 kg | 161.82 kg | 404.6 kg | 809.1 kg | 1,618.2 kg |
| Metres | 6 m | 30 m | 60 m | 150 m | 300 m | 600 m |
How much load does the 177.8 × 1.8 round tube take?
Supported at both ends, with the load at midspan: how many kilos it takes before it bends more than 1/200 of the span (what windows and light structures usually accept) or goes past the elastic limit of 6063-T5 aluminium.
| Span | 0.5 m | 1 m | 1.5 m | 2 m |
|---|---|---|---|---|
| Load at midspan | 4,595 kg* | 2,300 kg* | 1,530 kg* | 1,150 kg* |
Moment of inertia 385.4 cm⁴; section modulus 43.35 cm³. * Here the strength of the material governs, not the deflection. A guidance calculation for a straight beam with sharp corners, E = 69 GPa, without its own weight or buckling of thin walls: for a structure, the check must be done by an engineer.
