Question

Give reasons as to why telephone wires are kept slightly loose when they are laid in summer.

Answer 1

Hint: The above problem can be resolved by applying the concept of telecommunication technologies. Along with this, the impact of temperatures on such devices is to be analysed. Moreover, the effect of various parameters to cause smoother functioning of the devices are also taken into consideration.


Complete step-by-step solution
The telephonic devices are one of the most importantly used communication devices that can be used for both domestic and professional purposes. The wires of the telephones had the adverse impact of weather on its wire or the communication cables. It is generally observed that the telephonic wires are kept loosened when they are laid in the summer season. This is mainly because it can withstand the heat interaction in summer and avoid damage due to high temperature. During the summer season, the thermal energy accumulation leads to loosening of the anchors. That is why the wires are kept loose in summer seasons.


Note: In order to resolve the given problem, the key term to remember is the concept of thermal expansion and thermal resistance. The communication cables are made up of different materials, to make them sustainable to higher temperatures. Thus, some factors must be enlisted for which the devices' sustainability is maintained for a longer period.
