What is Tension (mechanics)?
'''Tension''' is a [[reaction]] [[Force (physics)|force]] applied by a stretched [[string]] ([[rope]] or a similar object) on the objects which [[wikt:stretch|stretch]] it. The direction of the force of tension is [[parallel]] to the string, towards the string. Tension exists also inside the string itself: if the string is made up of two parts, tension is the force which the two parts of the string apply on each other. The amount of tension in the string determines whether it will break, as well as its [[vibrating string|vibrational]] properties, which are used in [[string instrument|musical instruments]]. ==Related pages== {{Commonscat|Tension}} * [[Force (physics)]] * [[Pulley]] * [[Stress (physics)]] [[Category:Force]] [[Category:Mechanics]] {{physics-stub}}
