District of Columbia Mechanical and Ethics 20 PDH Discount Package 2

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 course presents the basic principles of hydraulics and pneumatics along with their various components followed by discussing the maintenance procedures associated with these systems.

In automotive and construction equipment, the terms “hydraulic” and “pneumatic” describe a method of transmitting power from one place to another through the use of a liquid or a gas which obey certain physical laws and principles discussed in this course.

This online engineering PDH course explains the operation of centrifugal and positive displacement pumps. In general a pump is a mechanical device that is used to raise the flow of a fluid from one elevation to the other by increasing the pressure of the fluid.

Centrifugal pumps use a centripetal force, which is defined as the action that causes the fluid to move away from its center of rotation. Where as positive displacement pumps physically entrap a quantity of liquid at the suction of the pump and push that quantity out the discharge of the pump.

This 3 PDH online course is applicable to mechanical engineers, plant operators, maintenance personnel, and technical staff who are interested in gaining a better understanding centrifugal and displacement pump design and operation.

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 PDH course provides a basic understanding of cooling towers, describes their key components and provides recommendations on how to improve the water efficiency.

Cooling towers are an integral component of many refrigeration systems, providing comfort or process cooling across a broad range of applications. They are the point in the system where heat is dissipated to the atmosphere through the evaporative process, and are common in industries such as oil refining, chemical process­ing, power plants, steel mills, and many different manufacturing processes where process cooling is required.

This online engineering PDH course introduces engineers to the National Society of Professional Engineers Code of Ethics. The Code provides ethical guidance to engineers in their various and often simultaneously held roles as 1) guardians of public health, safety, and welfare 2) employees, 3) employers, and 4) providers of technical service to clients.

Engineers practicing their profession encounter not only technical issues but also ethical issues. Sometimes the latter issues are easy to resolve: applying everyday, common-sense notions of honesty, openness, responsibility, and lawfulness is sufficient to guide the engineer to the appropriate decision. At other times, however, matters are more complicated. In particular, knowing what to do when two or more duties or obligations conflict can be difficult. For example, an engineer's duty to his client or employer may conflict with the engineer's duty to the general public. Codes of ethics have been formulated to help engineers address these conflicts.

This 1 PDH online course is intended for all engineers who are interested in gaining a better understanding about how to protect and respect their engineering profession in the utmost manner.
