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.

Ⅰ. 서론
현재 전 세계의 항공기 사업은 크게 미국의 보잉과 유럽의 에어버스로 양분되고 있습니다. 두 회사는 항공기를 개발함에 있어서 다른 철학과 미래 전망으로 각자의 특징을 가지는 비행기를 개발하지만 두 업체의 지향하는 바는 같습니다. 바로 낮은 연비를 가지는 고효율의 비행기를 개발

H2SO4 + H2O H2SO4 (aq)
The Fate of Atmospheric SO2: Acid Rain
[HSO3-] = [H+]
and
Ka = 1.7 x 10-2 = [HSO3-][H+] = [HSO3-]2
[H2SO3] 1.0 x 10-7
[HSO3-] = 4.1 x 10-5 M
So the ratio of HSO3- to H2SO3 is 410:1 (4.1 x 10-5 /1.0 x 10-7).
Because [HSO3-] = [H+] = 4.1 x 10-5 M
③ Environmentally-responsible aviation : By March 2010, EU-based airlines must provide carbon dioxide emission reports. That’s why, over the last six months, several EU airlines have begun using bio-fuel either wholly or in part on certain routes. This trend is now spreading to North America where several airlines have indicated their interest in buying eco-friendly jet fuel.

ROA and ROE of HSBC
For the next asset analysis we are considering data from the period 2004-2009. First let´s take a look to the principal ratios of the company. ROA ratio for HSBC has decreased since 2007 and this tendency has continued indicating that the bank efficiency to produce profits has diminished. This is mainly due to the rise in operating expenses by 12% that reflected increased
