静态横梁模型

Beam Statics Model - Equivalent Loads, Torques and Reactions

《工程模型》
静态横梁模型
Beams are a common structural component,
横梁是建筑结构中常见的部分
and the beam statics model
横梁静态模型
helps students to understand how they work.
可以帮助学生们了解横梁的工作原理
As they build the model, students
学生们建造模型时
learn about reactions, supports and beams.
可以学习反作用力 支撑力以及横梁的知识
They also learn about forces and moments,
他们还会学习力和力矩
and about the difference between dead and live loads.
以及静负载和动负载之间的差异
The model is instrumented in such a way
模型的这种构造方式
that students can move loads along the beam
使学生可以沿着横梁移动负载物
and see how doing so affects the reactions.
并观察这样操作对反作用力的影响
If a torque is applied to the beam,
如果在横梁上安装一个转矩
students can see firsthand
学生们可以直接观察到
that where it is applied does not affect the reactions —
安装转矩的位置不会对反作用力产生影响——
a counter-intuitive fact
这与人们的直觉不符
that they might otherwise find difficult to accept.
若非亲眼所见 他们很难接受这一事实
Students can also see
学生们也可以观察到
how distributed loads and equivalent point loads
分布载荷和等效的集中载荷如何
produce the same reactions (within experimental error).
产生相同的反作用力(在实验误差范围内)
If students know how to calculate reactions,
如果学生们知道如何计算出反作用力
they can do so,
他们也可以这样做
and they can compare their calculated reactions
并且可以将他们的计算结果
with the measured ones.
与测量结果进行对比
