学生要确定两个横截面面积相同而形状不同的铝梁实验样本的相对刚度，并研究结果如何与理论一致。

Students will determine the relative stiffness of two aluminum beam test specimens of equal cross sectional area but different cross-sectional shape and see how they conform to theory.

由于其横截面积相对小，不能承受大的应力，所以点焊处容易产生裂纹。

Of their relatively small cross sectional area , which does not allow them to sustain high stress.
