Ⅰ. 암석(돌)의 조직
암석의 작은 조각(장경 10㎝ 이하)이나 현미경하에서 관찰되는 암석의 조직(texture)은 광물 또는 비결정질(유리)이 모여서 나타내는 특징으로서 화성암의 색과는 직접적인 관계가 없다. 화성암을 기재하는데 중요한 몇 가지를 들면 다음과 같다.
1. 현정질조직(phaneritic texture)

정역학(statics)의 일반 원리를 응용하여 구조물이 외력을 받을 경우 그 내부에 어떠한 힘-구조물에 발생되는 내력(internal force)-이 생기는가, 또 어떻게 변형(deformations) 하는가를 연구하는 응용역학의 한 분야.
2) 재료역학(mechanics of materials)

1 Introduction
When designing an aircraft, it’s all about finding the optimal proportion of the weight of the vehicle and payload. It needs to be strong and stiff enough to withstand the exceptional circumstances in which it has to operate. Durability is an important factor. Also, if a part fails, it doesn’t necessarily result in failure of the whole aircraft.
The main sections of an aircra
1.General
Most of the aircraft operating today are made with lightweight but strong aluminum, with most newer aircraft being made of advanced composites.
Note the Cirrus SR-22 and Boeing Dreamliner 787 as examples of the newest modern aircraft developed at this time.
It has only been very recently that mainstream automobiles are starting to switch to lighter materials like aluminum.
