화살표가 있는 대칭 막대

Question

x지정된 길이와 축의 각도를 가진 두 개의 막대가 표시되고 원점에 원이 표시되는 아래와 같은 플롯을 갖고 싶습니다 . 게다가 원점에 표시된 두 개의 화살표. 이 도식적인 그림을 그릴 수 있다면 Tikz숙제에 대한 몇 가지 질문을 매우 그림 같은 스타일로 제공할 수 있을 것입니다.

Answer 1

이 중 특별히 복잡한 것은 없습니다. 물건 dimline의 출처는여기. siunitx치수와 각도를 조판하는 데 사용할 수 있습니다 .

여기서는 범위 내에서 전체를 회전하는 것이 합리적일 수 있습니다.
