4.1. Wing structure
Wing structure
The wing on the plane is a part that the highest load take. The large bending moments especially act on the point near the root of wing. Also, we should consider the number of spar, rib, position, skin thickness and taper ratio.

Beam theory shows that the I-shaped section is a very efficient form f

Solid Source
each cell is loaded with a charge material, usually a pure element like gallium or arsenic, which is solid at room temperature.
The gaseous atomic or molecular beam is generated by heating the charge in the effusion cell in the growth chamber.
The effective beam pressure or flow rate of the gas, called the beam flux, is varied by adjusting the effusion cell temperature.

Crosstalk among neighboring interconnects
Capacitive crosstalk roughly proportional to kc=CIMD /CILD
⇒ Mainly fixed by the aspect ratio of lines and vias
⇒ Crosstalk level increases at each new generation
Induces delay uncertainty
