军舰抛锚后,锚拖着锚链沉入海底。由于锚链比水深要长几十倍,使锚身在海底平躺。当军舰在波浪的作用下缓缓移动时,在锚的自身重量及与锚杆一端连接的部分锚链的重量作用下,锚爪深深扎入海底沙石泥土之中,产生抓持力;同时,锚链的一部分在海底会产生摩擦力;再加上锚链本 After the warship broke down, the anchor dragged the anchor chain into the sea. As the anchor chain is several times longer than the depth of the water, the anchor body lies on the bottom of the sea. When the warship moves slowly under the action of the waves, the claw plunges deeply into the sand of the sea floor under the weight of the anchor and the weight of the part of the anchor chain connected with one end of the anchor rod to generate the gripping force; At the same time, part of the chain will create friction on the sea floor;
