Q28. Roof pole is braced by a steel rope in roof pole connection to
(A) Keep the pole firm
(B) Maintain shine of the pole
(C) Keep tensile stress low
(D) Keep the sag low
Answers
Answer:
To keep tensile stress low, the roof pole is braced by a steel rope as is done in the case of the stayed pole. If possible the roof pole should be fastened to the main truss of the roof construction. In case of 01 pipe connection 01 pipe is raised above the roof to a suitable height.

Extra Information:
A electrical line is that service line which distributes electric power from a utility pole to various customer buildings etc.
There are two types of service lines for electric power distribution => service drop and service lateral.
In service drop there are overhead electrical lines.
In service lateral there are underground electrical lines.
Roof poles are used for low roof or single storied building. If the height of pole goes above 3 meters then the tensile strength increases so, to keep it low roof pole is braced by a steel rope.
