The design of a machine includes many factors other than those of determining the loads and stresses and selecting the proper materials.
机械设计除了计算载荷和应力、选择合适的材料外，还包括许多其它因素。
When the biaxial nominal stresses are equal to each other, the mathematical relationship between loading strength and porosity can be also gained for the foamed metals under biaxial equal loads.
当双向承受的名义应力相等时，还可得到泡沫金属在双向等荷承载条件下的载荷强度与孔率的数学关系。
To solve these problems they concocted hypotheses on how beams, rods and plates behaved under stresses, pressures, or loads.
为了解决这些问题，他们关于梁、杆和板在应力、压力或负载下是怎样变动的提出了假设。
