已下翻译杜绝机译，请放心采用。 A force is a push or pull.The effect of a forceeither changes the shape or motion of a body or prevents other forces from making such changes.力就是推力或拉力。力的效应可以改变物体的形状或运动，也可以防止其它的力作出这样的改变。Every force produces a stress in the part on which it is applied.Forces may be producedby an individual using muscular acion or by machines with mechanical motion. 每一股力都会在其施加的部位（零件）产生应力。力可以由一个个人用肌肉动作或由机器的机械运动来产生。 Forces are produced by physical or chenical change,gravity,or changes in motion.力也可以由物理或化学的变化、重力、或运动的改变来产生。When a force is applied which tends to stretch an object,it is called a tensile force.A part experiencing a tensile force is said to be in tension.A force can also be applied which tends to shorten or squeeze the object.Such a force is a compressive force. 当施加一股趋于拉伸一个物体的力时，此力就称为拉伸力。受到拉伸力的部位（零件）就称为处于张力状态。也可以施加一股趋于缩短或挤压物体的力。这样的力就是压缩力。 A third force is known as a torsional force,or a torque since it tends to twist an object.Still another kind of force,which seems to make the layers or molecules of a material slide or slip on one another,is a shearing force. 第三种力就是众所周知的扭转力，或者称为转矩，因为它趋于使一个物体扭转。还有另一种力，它似乎能使材料的各层次或分子间相互滑移，这就是剪切力。 Each of these forces may act independently or in combination.For example,adownward force applied on a vertical steel beam tends to compress the beam,.这些力中的每一种力都可以单独作用，也可以综合作用。例如，一股施加在一根垂直钢梁上的向下力，有压缩该钢梁的倾向。If this beam is placed in a horizonal position and a load is applied in the middle,the bottom of the beam tends to stretch and is in tension.如果此梁放置在水平位置，而负荷施加在中间，那么梁的底部受到拉伸而处于张力状态下。At the same time,the top area is being pushed together in compression. If the compressive and tensile forces are greater enough to make the layers of the material slide upon each other,a shearing force results.同时，顶部区域则被向一起推而处于压缩状态。如果压缩力和拉伸力足够大，使得材料的各层次间相互滑移，那么就产生了剪切力。

So you say I'm better off hereAs dry as the shoreline所以你说我最好在这里直到海枯石烂In an ocean of fearSo you say I can't be aliveUntil there is nothingWhen we're meeting eyes again在这一个充满恐惧的海洋里，当我们眼神再次交汇，你说当什么都已不存在时我也将不能存在Day by day, I wander these hallsAnd you're casting a shadowOnto every wallBut all the way you ring in my ear日复一日，我漫步于这些殿堂，在这里的每一面墙上都有你的影子，你的声音在我耳边萦绕From the moment I knew you were leaving me here从那一刻开始我意识到你已离我远去You're leaving me hereYou're leaving me hereYou're leaving me here你已离我远去你已离我远去你已离我远去This give and take这种给予与带走This waiting on time这种不尽的等待It's this twisted up memory that I can't unwind我已无法从这段纠缠的感情中释怀These fragile words that fall from my mouth于是我说出了最伤人的话语I'm crumbling and crowded我正在濒临崩溃的边缘But I've figured you out但是我理解你I've figured you outI've figured you outI've figured you out我理解你我理解你我理解你The shoreline calls the sea海岸呼唤海洋For simple words and company为了简单的诺言和陪伴But words go on and on但是诺言在不停地不停地延续Til they collide and all is gone直至它们破碎，然后全部消失I dive into the deepInto the sea inside of me于是我把自己埋藏在只属于自己的深深的海洋里To find another song为了寻觅另一只歌To find a place where I belong为了寻觅一个属于我的地方The shoreline calls the sea海岸呼唤海洋For simple words and company为了简单的诺言和陪伴But words go on and on但是诺言在不停地不停地延续Til they collide and all is gone直至它们破碎，然后全部消失I dive into the deepInto the sea inside of me于是我把自己埋藏在只属于自己的深深的海洋里To find another song为了寻觅另一只歌To find a place where I belong为了寻觅一个属于我的地方
