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。
Force - measuring elements employ either a cantilever beam or a column arrangement.
测力元件采用悬臂梁或柱的形式。
For fixed damping and fixed excited frequency the motion of the beam under small amplitude of force is periodic, but becomes chaotic through period doubling bifurcation with increase of the force.
对固定的参数激励频率和阻尼，当参数激励幅值较小时梁的运动是周期的，但大幅值激励会使运动通过倍周期分岔变为混沌。
