Texas Mechanical and Ethics 15 PDH Discount Package 3

This online engineering course provides necessary information to understand the principles and theory of refrigeration, the components of mechanical refrigeration systems, and the types of refrigerants and associated equipment. This course also discusses the methods used for installing, maintaining, and repairing refrigeration equipment, including domestic refrigerators and freezers.

Refrigeration is the process of removing heat from an area or a substance. It is usually done by an artificial means of lowering the temperature, such as by the use of ice or mechanical refrigeration, which is a mechanical system or apparatus, designed and constructed to transfer heat from one substance to another.

This online engineering course presents the operational principles and basic mechanisms of the internal combustion engine.

The power of an internal combustion engine comes from burning a mixture of fuel and air in a small, enclosed space. When this mixture burns, it expands significantly; building pressure that pushes the piston down, in turn rotating the crankshaft. Eventually, this motion is transferred through the transmission and out to the drive wheels to move the vehicle.

The automobile is a familiar object to all of us. The engine that moves it is one of the most fascinating and talked about of all the complex machines we use today. This machine is what we call the internal combustion engine.

This online engineering PDH course provides an overview of gas turbines, by briefly discussing the basic theory, types, construction features, and operating principles of gas turbine engines.

The gas turbine is an internal combustion engine that uses air as the working fluid. The engine extracts chemical energy from fuel and converts it to mechanical energy using the gaseous energy of the working fluid to drive the engine.

The gas turbine, when compared to other types of engines, may offer many advantages. Its high power-to-weight ratio has made it the preferred engine for an aircraft. In terms of fuel economy, modern gas turbines may compete with diesel engines and be superior to boiler/steam turbine plants.

This engineering online PDH course will establish conditions under which, when an engineering failure has occurred, it can be attributed to negligence.    

Five causes of failure are proposed: negligence, rare failure mode, overlooked failure mode, new (previously unrecognized) failure mode, and incorrect assessment of a known risk. Negligence is the only cause that involves failing in an ethical duty.  These concepts are illustrated with five case studies of failures ranging from gross negligence to absolutely unforeseeable events: 1) the Great Boston Molasses Flood of 1919, for which a new possible cause was identified 95 years later (2014); 2) a building collapse in Bangladesh in which over 1,000 people died—one of the worst structural engineering disasters in history; 3) a meteorite strike of a private residence; 4) the crash of the British-French Concorde supersonic airliner, caused by an unlikely tire blow-out; and 5) radiation overdoses received by patients treated by the Thorac-25 medical linear accelerator, caused by errors in the software controlling the machine.
