关于材料力学中应力和转角计算的程序，另有简单的绘图(There are simple drawings for the procedures of stress and rotation in the mechanics of materials)

用于求解材料力学中的多种受力下的状态，包括挠度曲线绘制，应力应变分析等(It is used to solve the state of material mechanics under various stresses, including the drawing of deflection curve, stress-strain analysis and so on.)
