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。

These formulae give us the stress and strain in a prismatic beam when it is subjected to pure bending .
当棱柱形梁受纯弯曲时，这些公式给出了它的主力和主变。

The results show that stressin hollow beam and semi-shaft bush is much less than permissible stress, while joint of suspension frame and axle housing has too large local stress.
