How much do the lengths weigh?
| 6 m lengths | 1 | 5 | 10 | 25 | 50 | 100 |
|---|---|---|---|---|---|---|
| Weight | 4.08 kg | 20.4 kg | 40.8 kg | 102 kg | 204 kg | 408 kg |
| Metres | 6 m | 30 m | 60 m | 150 m | 300 m | 600 m |
How much load does the 15.87 square bar 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 | 36 kg | 8.9 kg | 4 kg | 2.2 kg |
Moment of inertia 0.53 cm⁴; section modulus 0.67 cm³. 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.
