Design
bell tent - simplified 12 sided design - dodecagon = 12 sides
π = pi = 3.14159 ...
√ = square root
a (side length) = 1.11 m
r (inradius (apothem)) = 2.07129 m
R (circumradius) = 2.14436 m
A (area) = 13.7948 m2
P (perimeter) = 13.32 m
x (interior angle) = 150°
y (exterior angle) = 30°
Walls
http://www.extremtextil.de/catalog/Nylon-siliconecoated-40den-90g-sqm-tent-fabric-2nd-choice::1694.html
Weight: app. 90 g/sqm
Cost: 4.40 EUR
height = 0.6m
conservative wall = 12 segments
segment length = 1.11m
area of each segment = 0.6 * 1.11 = 0.66m2
cloth = 1.5m = 2 segments wide. 12 segments / 2 = 6segments * 1.11 = 6.6m
cost = 6.6m * 4.40 = 29.04 EUR
weight = 90* (12 * 0.66) = 712.8g
Roof
http://www.extremtextil.de/catalog/Nylon-siliconecoated-40den-90g-sqm-tent-fabric-2nd-choice::1694.html
Weight: app. 90 g/sqm
Cost: 4.40 EUR
conservative estimate = 12 segment roof
each segment = 1.11 wide
isoceles triangle side = lots of fucking pythag
side cross section = a2 + b2 = c2 = 2071 (half width of tent) + 1800 (height of roof from wall) = 2743
roof segment = a2 + b2 = c2 = 550 (half the length of the side) + 2743 = 2797mm = 2.8m
each segment = 1.11 wide, one side of triange = 2.79m
total area of segment = 1.52m2
need 12 = 18.24m2
cloth = 1.5m = 2segments in sq formation = 12 /2 = 6 segments long = 6 * 2.79 = 16.74m long
cost: 16.74 * 4.4 = 73.66 EUR
weight = 18.24*90 = 1641.6g
Floor
A (area) = 13.7948 m2
Material - http://www.esvocampingshop.com/nl/tentdoek/ripstop-nylon/nylon-zwart-85-gr-m.html
Prijs: € 8,95
Breedte: 150 cm
Gewicht: 85 gr/m²
floor is 4.142m long
floor is 4.142m wide
cloth@1.5m breadth = 1.5x3 = 4.5 breadth's wide
cloth needs to be 4.142*3 long = 12.426m
13m at 8.95 eur = 116.35 EUR
weight = 85 * 13 = 1105g
Total
Cost: 29.04 + 73.66 + 116.35 = 219.05
Weight: 712.8 + 1641.6 + 1105 = 3458.8g = 3.5kg
Definitions
Den - It is defined as the mass in grams per 9,000 meters.
Tex - the mass in grams per 1000 meters.
