摘要
柔软链条对地面的压力随它和地面的位置关系而变化。当柔软链条落至地面时,它对地面的压力大于地面静止部分链条的重力,在柔软链条被竖直悬挂后自由释放过程中,它对地面的压力至少是静止部分链条重力的3倍;当柔软链条提离地面时它对地面的压力始终等于静止部分链条的重力,并与柔软链条的运动状态无关。
The pressure exerted by soft chain against ground changes in accordance with its position to ground. When soft chain falls on the ground, the pressure it sets against ground is bigger than the gravity of static part of chain on the ground. Furthermore, when soft chain is set upright, the pressure it exerts against ground is at least three times of gravity of static chain. When soft chain is raised clear of ground, the pressure against ground remains equal to the gravity of static part of chain, and has nothing to do with the moving state of soft chain.
