2、b = 450N/mm2 and length L=1m.The force can be got according to the proportion while different kind of plate and different length to be bent.0.87050403011108070601.21201008070601.5150120110908022201901701501301102.525022020017015013033302902502101801603.540033029025022020044403703302902602302104.5本表数
3、值是以材料强度b = 450N/mm2及长度L=1m计算而得，不同强度的材料及长度所需的折弯力可按相应的比例计算而得。47041037033030027024055104504003603303002702506520470430390360340300870064060052046042010810720650129507801413001100板料折弯力计算公式：Calculating Formula： P=650S2L/V（b = 450N/mm2）P折弯力 （千牛） P： Bending Force (kN)S板厚 （毫米） S： Thickness of the Plate (mm)
