【Abstract】 In this article, the numeric calculation method is used on a micro-computer to find the area of a horizontal trapezoidal cross-section of a lift hook,the center of gravity, and the coefficient of cross-section.Further,drafting software is used to draft the stress distribution curve of the horizontal tensile and compressive stresses of the cross-section. In this way,the designers’ workload can be lightened and the precision of the calculation increased.更多还原
