The objective is to verify the predictions of engineering beam theory in so far as that theory defines the centerline deflection and extreme values of the normal stress.
实验目的是证明现行的工程梁理论，这种理论定义了中心线变形和普通应力的极值。
I try a series of solutions, including intense focusing of my eyes and propping a flashlight on some books so that it casts its beam on my notes, but these remedies are unsatisfactory in the extreme.
我试了很多办法，包括睁着眼睛使劲瞅，在旁边的书上竖上手电筒，但最终效果都非常令人沮丧。
In fact as the fulling- mill was there, although not then in use, its beam moved with extreme power would serve to stretch out the wire by rolling it round itself.
压榨机就在这里，而且现在正闲着，只要用巨大的力量推动卷轴，它就可以把铁丝拉长并卷上去。
