在实际工程结构中,为了减轻结构重量和节省材料,有些杆件可以采用变截面,变截面杆件上作用非均布荷载时的函数积分比较困难,如果借助Mathematica软件进行数值计算则十分方便。虽然工程上变截面杆件应用不多,但作为理论探讨仍具有其实际意义。

In practical engineering structures,in order to reduce the structural weight and save materials,and some bars may use variable cross-section,and it is difficult to get functional integration for the role of variable cross-section bar when it works on the non-uniform load.But if Mathematica is used the numerical calculation becomes very easy.Although the variable cross-section bar is rarely used,but as a theoretical study it still has its practical significance.
