A uniform ladder of weight 850 N and length 6 m rests on a horizontal ground and leans against a smooth vertical wall. The angle made by ladder with horizontal is 65°, when a man of weight 750 N stands on ladder at a distance 4 m from top of ladder. The ladder is at point of sliding. Determine the coefficient of friction between ladder and the floor.

Cables

Cables are collections of wires, alternatively referred to as a cord, connector, or plug. They are one or more wires covered in a plastic covering that allows for the transmission of power or data between devices. The earliest use of recognizable electrical cable was the early commercialized telegraph lines. These were iron-made and tedious to produce and install cabling.
