Because the leaves on a tree branch all grow at the same end of the branch, Eloy modeled the force of wind blowing on a tree's leaves as a force pressing on the unanchored end of a cantilevered beam.
由于同一根树枝上的叶子都长在同一侧,因此在埃洛伊的模型中,作用于树叶的风力都施加在这一悬臂结构的非固定端。
The sails are mounted at an angle or are given a slight twist, so that the force of wind against them has two components, one of which, in the plane of the sails, causes rotation.
风叶有一个安装角或略有扭曲,因此可将吹来的风分解为两个分力,其中在风叶平面上的分力使风车旋转。
