How much do the lengths weigh?
| 6 m lengths | 1 | 5 | 10 | 25 | 50 | 100 |
|---|---|---|---|---|---|---|
| Weight | 5.77 kg | 28.83 kg | 57.66 kg | 144.2 kg | 288.3 kg | 576.6 kg |
| Metres | 6 m | 30 m | 60 m | 150 m | 300 m | 600 m |
How much load does the 67.5 × 40 × 2.5 U channel 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 (67.5 mm high) | 825 kg* | 410 kg* | 195 kg | 110 kg |
| Flat (40 mm high) | 215 kg* | 97 kg | 43 kg | 24 kg |
Moment of inertia 26.22 cm⁴ upright · 5.76 cm⁴ flat; section modulus 7.77 cm³ upright · 2.04 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.
