### Company History

*Adaptive Allotropy made their first breakthough in transparent silicon bucky-structures in the late 2030s. Fortunately unmanned test mission saw these windows explode after a mere 6 minutes in Low earth orbit, and led to a further 6 years of painstaking research before their certification of mission use.*

### Company Product Summary

^{2}, windows provide adequate radiation and thermal insulation, however they are prone to brittle failure.

### Relevant Physics for Product

The maximum stress within the window pane can be calculated using the following equation for square windows: σmax = (Δp L2) / (2 t2) where Δp is the pressure difference in Pa, L is the span in m, t is the thickness in m, and σmax is the maximum allowable tensile stress in the material, 290.1 MPa. For circular windows, the equation is σmax = (3Δp D2) / (4 t2) where D is the diameter in m. Windows may be ordered in other shapes and when justifying the thickness for these, you can approximate the window as square and replace L2 by multiplying the longest dimension of the window by its longest perpendicular component.

The equations outlined above have been obtained using Kirchhoff Plate Bending Theory for plates with clamped edges under uniform pressure loads (typically a second or third year topic at university). If you want to read up about this theory and see the derivation for circular plates, please look at this Wikipedia page.

Solar intensity refers to the amount of energy received from the sun in a given unit area across the entire electromagnetic spectrum. This is important for thermal considerations, as well as for the design of things such as solar panels which generate their power from this sunlight.
