This mechanical force might be in comparison to sending pressurized water by way of a fireplace hose – the conductor will endeavor to straighten alone developing a harm issue for splice fittings, fasteners, or perhaps the conductor itself.
Why can’t we put metallic objects in the microwave? How can electrical power transmission strains withstand a life time of publicity to the elements? What's the operate of the hydraulic bypass valve?
