A circuit breaker is supposed to protect the more valuable component the circuit is connected to. Too low a resistance, a minor glitch (spike) will break the circuit and stop the device from working. Too high a resistance, no glitches, no matter how large (a child sticking a paper clip into the wall sockets, for example), will break the circuit and the device (child) may get damaged. Each circuit will have a purpose (power load), and the circuit breaker should be chosen for that purpose with some tolerance. A free standing closed circuit breaker should have no resistance across its internal contacts. The main purpose of a circuit breaker is to protect the conductors that supply the load. If the current going to the load becomes greater that the amperage rating of the wire the circuit will open thereby saving the conductors from damage. Once the load current is below the wire rating ampacity, the breaker can be reset for normal operation.

Engineering in tractors can easily be seen with all modern tractors basically being seen with 4wd and a cab with air conditioning. The best way to track engineering is through the John Deere Combine. In the sixties it was all manualy adjusted then seventies some adjustments were moved to the cab. Eighties more adjustments were moved into the cab but you still had to moniter the dirt in the grain and how much grain was being lost. The nineties brought sensors tracking the amount of grain lost and it can be adjusted in the cab. The newest models have sensors and adjustments all connected to a computer and the computer tracks grain loss and makes adjustments without operator imput.

A chiller plant normally consists of evaporator pumps, chillers, condenser pumps, and cooling towers.

The evaporator pumps pump chilled water out to the building through a water pipe loop to air handler units that use valves to vary the amount of chilled water to that unit's water coil to control the temperature of the air coming out of the unit. Thus added heat back into the water that goes back to the plant.

The return water from the building goes to the evaporator side of the chillers & they cool it back down, transferring the heat to the condenser side of the chillers, which is a separate water loop.

The condenser pumps pump the condenser water out to the cooling towers, which are outside. The water is pumped to the top of the tower & then rains down inside it. There are big fans on the top of the tower that pulls air through the tower, thus across the raining water & blows it outside. This water pools up at the bottom of the tower & is sucked back into the building to run through the condenser side of the chillers again, thru removing the heat from the building.

In order to work as an Engineer you need at least a Bachelors degree in Engineering. This type of degree can take any where from 4-5 years depending on the University program. However to advance in the work force it is a good idea to have a Masters degree.

Yes they do.

An equipment is any laboratory experiment material which mechanically uses current like a pH meter,electric weighing machine etc while apparatus is any other laboratory experiment material which doesn't mechanically use current like thermometers ,burette ,pipette,

Bridges over rivers were made in prehistoric times.

For the most part, Tugboat Engines are LARGE two stroke (or two stroke cycle) Diesel Engines which provide High Combustion Temperatures and Pressures, High Horsepower typically > 1000 and High Torque, at relatively low speed.

As an example of the two stroke diesel cycle engines ability to produce high horsepower and high torgue at low speed, The Union 6V Diesel was produced during World War Two as an engine for locomotives for the transport of industrial materials used in the production of weapons and armament. It was functionally an inline or straight block configuration, but because adjacent cylinders were actually offset from centerline by 6 degrees in opposite directions (cyl 1 offset to starboard by 6 deg from centerline and cyl 2 offset to port by 6 degrees from centerline, and so on) it was technically a V configuration. It was subsequently utilized by the Navy in a few instances as main propulsion for Yard Craft, mostly Yard Oilers (capable of hauling around 240K to 280K gallons of fuel to be loaded to ships at dock in a given harbor).

This engine produces in excess of 1000 horsepower at a maximum 325 RPM. It idles at 125 RPM, and at that idle speed produces very large smoke rings out it's exhaust stack. This was also a naturally aspirated diesel (meaning it had no blower or turbocharger). It was also a directly reversible engine in that to reverse your direction of travel, the engine had to be shut down, the camshaft shifted utilizing a dual direction air cylinder, a pinion gear mechanically moved into position between the starter gear and the flywheel gear, and the engine then was restarted in the opposite rotation, turning the main output shaft in the opposite direction. No transmission or reduction gear.

Channel spacing is the difference in the frequency allocation of the allocated frequency plan to avoid overlap between the channels or frequencies.

For branching of one size lesser of run pipe, Stub On is preferred. For other branching

less than one size of run pipe stub in is preferred. The Design is based on ANSI B 31.3

iterative impedance is a particular value of the load impedance that can be found which will produce an input impedance having the same value as the load impedance.When connected at one end of the port produces an equal impedance when looking at the other.

Image impedance-Two impedance's of two port network,which will terminate the port simultaneously in a way that, at each port the impedance seen in both directions are equal.

They send the sound in, it ricoches of the sides of the pipes which tells them how thick, thin and long they are. This is 95% accurate.

To me the most interesting type of engineering is the electronics engineer.Electronics engineering involves a lot of mathematics and physics and would seem very easy to someone who is very good in maths and physics,But would seem hard for anyone that is not good in maths and physics

1. Models help us to visualize a system as it is or as we want it to be.

2. Models permit us to specify the structure or behavior of a system.

3. Models give us a template that guides us in constructing a system.

4. Models document the decisions we have made.

Discrepant material is material or product that does not meet specified requirements (also called non-conforming material).
