Assignment on Threaded jointsDue date:__________________ ___________________ ________________ Surname Given names IDA power line tower is erected to support a high-voltage power line (see figure below),which includes six phase conductors and three Earth shield wires. The tower isfabricated as a steel structure resting on four square supporting feet bolted to aconcrete foundation with four Anker bolts at each support (see figure below). Theresultant tension force FT from cables on each side of the tower is applied at point m,and can be at 60o to the horizontal plane (sagging downwards) if the tower is installedon a plane or at 30o to the horizontal plane pointed upwards if the tower is installed on ahilly landscape. The gusty wind load, which could be represented with a resultant forceof Fw is applied at the geometric centre of the tower n in any direction in the horizontalplane (see figure below) and tends to shift the tower sideways and topple it. In the caseof an accident when all…
