克劳德在《最终幻想7》里把破坏剑舞得虎虎生风，曾经在《流言终结者》登场的机械工程师 Allen Pan 和他的团队最近也自制了一把破坏剑，但发现勉强抬起这一块巨大铁块已经是极限了。为了舞动这把山寨破坏剑，Allen Pan 去搞了一套机械外骨骼。视频地址这把山寨破坏剑重量是 50 磅，换算成公制单位大约是 22.7 公斤，也就是 50 市斤不到，似乎也没有非常重。然而，挥动破坏剑时，施力的位置不是在物体的重心，而是在靠近末端的位置。根据现实世界的物理法则，偏移的重量会促使剑围绕较靠近重心的那只手旋转。这种旋转的趋向被称为「力矩」。山寨破坏剑手柄末端的施力点距离剑的重心约 3 英尺，按照公式换算，以靠近剑重心那只手为支点，用远离重心那只手发力，产生了约 150 英尺磅的力矩。换言之，就算忽略作为支点那只手用的力，
Claude dances the sword of destruction in "Final Fantasy 7". Allen pan, a mechanical engineer who once appeared in "the terminator of rumors" and his team recently made a sword of destruction, but found that it was the limit to lift this huge iron block. In order to dance this fake destruction sword, Allen pan went to build a mechanical exoskeleton. Video address: the weight of this Shanzhai destruction sword is 50 pounds, which is about 22.7 kilograms in metric units, which is less than 50 Jin. It doesn't seem to be very heavy. However, when wielding the destruction sword, the position of applying force is not at the center of gravity of the object, but near the end. According to the laws of real-world physics, the weight of the offset causes the sword to rotate around the hand closer to the center of gravity. This tendency to rotate is called "torque.". The force application point at the end of the handle of the Shanzhai destruction sword is about 3 feet away from the center of gravity of the sword. According to the formula conversion, take the hand close to the center of gravity of the sword as the fulcrum, and use the hand far away from the center of gravity to generate about 150 foot pounds of torque. In other words, even if we ignore the force of the hand as the fulcrum,
