《工程力学专业英语》章节摘录[E]
Tension.Tension is the general name for a force that a rope，stick，etc. ，exerts when it is pulled on.Every piece of the rope feels a tension force in both directions，except the end point，which feels a tension on one side and a force on the other side from whatever object is attached to the end.
In some cases，the tension may vary along the rope. The“Rope wrapped around a pole”example is a good illustration of this.In other cases，the tension must be the same everywhere.For example，in a hanging massless rope，or in a massless rope hanging over a frictionless pulley，the tension must be the same at all points， because otherwise there would be a net force on at least one tiny piece，and then F=ma would yield an infinite acceleration for this tiny piece. Normal force. This is the force perpendicular to a surface that the the surface appliesto an object. The total force applied by a surface is usually a combination of the normal force and the fric.tion force. But for frictionless surface such as greasy ones or ice，only the normal force exists. The normal force comes about because the surface actually compressesa tiny bit and acts like a very rigid spring. The surface gets squashed until the restoringforce equals the force the object applies.
Remarks： For the most part，the only difference between a “tension”and a“normalforce”is the direction of the force. Both situations can be modeled by a spring.， In the caseof a tension，the spring （a rope，a stick，or whatever）is stretched，and the force on thegiven object is directed toward the spring.In the case of normal force，the spring is compressed，and the force on the given object is directed away from the spring.Things likesticks can provide both normal forces and tension. But a rope，for example，has a hard timeproviding a normal force.
In practice，in the case of elongated objects such as stick，a compressive force is usuallycalled a6'compressive tension，or a negative tension，instead of a normal force.So bythese definitions，a tension can point either way. At any rate，it's just semantics. If youuse any of these descriptions for a compressed stick，people will know what you mean.
Friction. Friction is the force parallel to a surface that a surface applies to an object.Some surfaces，such as sandpaper，have a great deal of friction. Some，such as greasy ones，have essentially no friction. There are two types of friction，called 66kinetic" friction and“static”friction.
Kinetic friction deals with two objects moving relative to each other.It is usually agood approximation to say that the kinetic friction between two objects is proportional tothe normal force between them. The constant of proportionality is called flk （the“coefficient of kinetic friction”），where pkdepends on the two surfaces involved.Thus，F=UkN，where N is the normal force. The direction of the force is opposite to the motion.
Static friction deals with two objects at rest relative to each other. In the static case，we have F≤usN （where ，us is the “coefficient of static frictio”）.Note the inequality sign.
