Major concentrations of Engineering

Engineering Design

Engineering design involves practical problem solving, research, development, and invention and requires designing, drawing, building, testing, and redesigning.

 

  • Identify and explain the steps of the engineering design process, i.e., identify the problem, research the problem, develop possible solutions, select the best possible solution(s), construct a prototype, test and evaluate, communicate the solution(s), and redesign.

 

  • 1.2 Demonstrate knowledge of pictorial and multi-view drawings (e.g., orthographic projection, isometric, oblique, perspective) using proper techniques.

 

  • 1.3 Demonstrate the use of drafting techniques with paper and pencil or computer aided design (CAD) systems when available.

 

  • 1.4 Apply scale and proportion to drawings, e.g., 1/4"=1'0"

 

  • 1.5 Interpret plans, diagrams, and working drawings in the construction of a prototype.

Construction/Structures

Various materials, processes, and systems are used to build structures.

 

  • Distinguish among tension, compression, shear, and torsion, and explain how they relate to the section of materials in structures

 

  • 2.2 Identify and explain the purposes of common tools and measurement devices used in construction, e.g., spirit level, transit, framing square, plumb bob, spring scale, tape measure, strain gauge, venturi meter, pitot tube.

 

  • 2.3 Describe how structures are constructed using a variety of processes and procedueres, e.g., welds, bolts, and rivets are used to assemble metal framing materials.

 

  • 2.4 Identify and explain the engineering properties of materials used in structures, e.g., elasticity, plasticity, thermal conductiviey, density.

 

  • 2.5 Differentiate the factors that affect the design and building of structures, such as zoning laws, building codes, and professional standards.

 

  • 2.6 Calculate quantitaively the resultant forces for live loads and dead loads.

Fluid Systems

Fluid systems are made up of liquids or gases and allow force to be transferred from one location to another. They also provide water, gas and oil, and remove waste. They can be moving or stationary and have assocated pressures and velocities.

 

  • 3.1 Differentiate between open (e.g., irrigation, forced hot air system) and closed (e.g., forced hot water system, hydroponics) fluid systems and their components such as valves, controlling devices, and metering devices.

 

  • 3.2 Identify and explain sources of resistance (e.g., 45 elbow, 90 elbow, type of pipes, changes in diameter) for water moving through a pipe.

 

  • 3.3 Explain Bernoulli's Principle and its effect on practical applications, i.e. airfoil design, spoiler design, carburetor.

 

  • 3.4 Differentiate between hydraulic and pneumatic systems and provide examples of appropriate applications of each as they relate to manufacturing and transportation systems.

 

  • 3.5 Explain the relationship between velocity and cross-sectional areas in the movement of a fluid.

 

  • 3.6 Solve problems related to hydrostatic pressure and depth in fluid systems.


Thermal Systems

Thermal systems involve transfer of energy through conduction, convection, and radiation, and are used to control the environment.

 

  • Differentiate among coduction, convection, and radiation in a thermal system, e.g., heating and cooling a house, cooking.

 

  • 4.2 Give examples of how conduction, convection, and radiation are used in the selection of materials, e.g., home and vehicle thermostat designs, circuit breakers.

 

  • 4.3 Identify the differences between open and closed thermal systems, e.g., humidity control systems, heating systems, cooling systems.

 

  • 4.4 Explain how environmental conditions influence heating and cooling of buildings and automobiles.

 

  • 4.5 Identify and explain the tools, controls, and properties of materials used in a thermal system, e.g., thermostats, R Values, thermal conductivity, thmperature sensors.

Electricity

Electrical systems genrate, transfer, and distribute electricity.

 

  • 5.1 Describe the different instruments that can be used to measure voltage, e.g., voltmeter, multimeter.

 

  • 5.2 Identify and explain the components of a circuit including a source, conductor, load, and controllers (controllers are switches, relays, diodes, transistors, integrated circuits).

 

  • 5.3 Explain the relationship between resistance, voltage, and current (Ohm's Law).

 

  • 5.4 Determine the voltages and currents in a series circuit and a parallel circuit.

 

  • 5.5 Explain how to measure voltage, resistance, and current in electrical systems.

 

  • 5.6 Describe the differences between Alternating Current (AC) and Direct Current (DC).

Communications

The application of technical processes to exchange information includes symbols, measurements, icons, and graphic images.

 

  • 6.1 Identify and explain the applications of light in communications, e.g., reflection, refraction, additive, and subtractive color theory.
  • 6.2 Explain how information travels through different media, e.g., electrical wire, optical fiber, air, space.
  • 6.3 Compare the difference between digital and analog communication devices.
  • 6.4 Explain the components of a communication system, i.e., source, encoder, transmitter, receiver, decoder, storage, retrieval, and destination.
  • 6.5 Identify and explain the applications of laser and fiber optic technologies, e.g., telephone systems, cable television, medical technology, and photography.

Manufacturing

Manufacturing processes can be classified into six groups:

 

  • Casting and molding
  • Forming
  • Separating
  • Conditioning
  • Assembling
  • Finishing

 

7.1 Explain the manufacturing process of casting and molding, forming, separating, conditioning, assembling, and finishing.

 

7.2 Differentiate the selection of tools and procedures used in the safe production of products in the manufacturing process, e.g., hand tools, power tools, computer aided manufacturing, three-dimensional modeling.

 

7.3 Explain the process and programming of robotic action utilizing three axes.
