Here is a look at my device looking down the arm. Now I can calculate the thickness of this container. In my web container design, I will let the cartridge go back 10 cm along my arm. What would this look like if it fit around a wrist? If I use my own wrist for a basis, then I find that it has a circumference of 16.5 cm. That gives a total volume (per hand) of 0.00314 m 3. In that case, we can find the web volume estimation by a factor of 50. If I were Spider-Man, that’s what I would want. Well, then how big of a container would he need to have a reasonable number of shots? Let’s say he wants 50 uses of the web for each hand. That’s a long pencil and remember, that’s for just one of his typical web shots. If all of this webbing was put into a pencil, the pencil would be 3.2 m long. How about a comparison to the volume of a standard pencil with a radius of 0.25 cm. That might be a little difficult to visualize in terms of the size. This would put the total web volume for one use at 6.28 x 10 -5 m 3. Well, the steel cable could work but it would have to be much thicker with a radius of 2.5 mm. Carbon nanotube rope: 1.98 x 10 5 Newtonsīased on these calculations, it looks like carbon nanotube rope is the only thing that would work. If I replaced the web with real materials of the same size, this would be their maximum tension (based on the values from Wikipedia). Let me approximate the web shot from Spider-Man as a cylindrical shape with a radius of 1 mm. Here comes the first wild estimate (ok, not the first). In order to get a maximum tension, you need to know the cross sectional area of the wire since obviously thicker wires are stronger. This is the maximum tension per cross sectional area that the material can withstand before breaking and is measured in units of MPa (mega Pascals - or 10 6 Newtons/m 2. The strength of a material can be describe by the ultimate tensile strength. Let’s use this value to make a comparison to other web-like options.
