Because the horizontal tension is the same all the way along the wire. It must be, or the wire would move.SillyYak said:why would the tension at the center be equaled to the horizontal component of the tension at the post?
Tension in telephone wires is caused by the weight of the wire itself, as well as the weight of the poles and other structures that support the wire. Wind and weather conditions can also contribute to tension in the wire.
Excessive tension in telephone wire can cause the wire to stretch and sag, which can lead to poor signal quality and even disconnection. On the other hand, too little tension can cause the wire to break or become loose, also affecting signal quality.
The tension in telephone wires is measured using a device called a tensiometer, which uses a spring balance to measure the force applied to the wire. This measurement is usually expressed in pounds or kilograms.
Yes, tension in telephone wires can be adjusted by using devices such as tensioners or turnbuckles to tighten or loosen the wire. This is important in maintaining the proper tension for optimal signal quality.
Yes, there are safety concerns related to tension in telephone wires. If the tension is too high, the wire can snap and cause injury or damage. It is important to follow proper safety protocols when working with telephone wires and to have a professional handle any adjustments to tension.
