How much do the lengths weigh?
| 6 m lengths | 1 | 5 | 10 | 25 | 50 | 100 |
|---|---|---|---|---|---|---|
| Weight | 10.56 kg | 52.8 kg | 105.6 kg | 264 kg | 528 kg | 1,056 kg |
| Metres | 6 m | 30 m | 60 m | 150 m | 300 m | 600 m |
How much load does the 108.7 × 55 × 2 rectangular 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 |
|---|---|---|---|---|
| Upright (108.7 mm high) | 1,970 kg* | 985 kg* | 655 kg* | 425 kg |
| Flat (55 mm high) | 1,350 kg* | 590 kg | 260 kg | 150 kg |
Moment of inertia 100.88 cm⁴ upright · 34.97 cm⁴ flat; section modulus 18.56 cm³ upright · 12.72 cm³ flat. * 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.
