How can a breaker work on 60Hz and 50 Hz supplies?

A circuit breaker is like an automatic switch, designed to break a circuit if the current flowing (measured in amps) exceeds a predetermined maximum amount. The frequency at which the alternating current is changing is not relevant provided it is the normal one for which the circuit breaker has been designed to operate. In USA, Canada and other countries using similar power supply standards, that frequency is 60 Hz. In Europe and other world areas using similar power supply standards, that frequency is 50 Hz. A circuit breaker designed for use on 50 Hz or 60 Hz supplies should not be used to protect a circuit in a ship or aircraft running on a 400 Hz supply because its magnetic and capacitive components may not operate correctly. For such applications a circuit breaker designed to operate at 400 Hz must be used.


What is the main frame or body of a ship?

The main frame or body of a ship is called the hull. It is the watertight body of a ship that provides structure and buoyancy. The hull determines the ship's stability, strength, and seaworthiness.


What is formula for block coefficient?

The block coefficient (CB) is calculated as the ratio of the underwater volume of a ship's hull to the volume of a rectangular block that has the same overall length, breadth, and draft as the ship. The formula for block coefficient is: [ CB = \frac{V_{ship}}{L \times B \times T} ] Where: CB = Block coefficient Vship = Underwater volume of the ship's hull L = Length of the ship B = Breadth of the ship T = Draft of the ship


Does thrust help a ship to float?

No, thrust does not help a ship float. A ship floats due to the principle of buoyancy, which is a result of the displacement of water by the ship's hull. Thrust is used to propel the ship through the water.
