Study Notes
History of Engineering
- 1957: Sputnik, the first satellite, orbited Earth, sending signals back.
- April 1961: Yuri Gagarin became the first human in space aboard Vostok-1.
- May 1961: Alan Shepard, the first American, flew into space.
- 1963-1972: The Apollo program aimed to land humans on the Moon and return them safely.
- 1969: Neil Armstrong walked on the Moon.
- 1981-2011: The space shuttle program transported astronauts and contributed to the International Space Station.
- 2004: SpaceShipOne, a private company, achieved a successful human spaceflight.
Engineering Careers
- STEAM: Science, Technology, Engineering, Arts, and Mathematics are combined to solve problems.
- Diverse fields exist: Electrical, computer, mechanical, aerospace, civil, and chemical engineers each address specific challenges.
- Each specialty utilizes unique tools and materials to achieve different engineering aims.
Engineering Design Process
- Problem definition is the initial stage.
- Criteria and constraints must be considered.
- Research, brainstorming, and selection of solutions follow.
- Design and construction phases are crucial.
- Testing, redesigning/rebuilding, and final implementation culminate the process.
Materials and Processes
- Two main wood types: hardwoods and softwoods.
- Softwoods are generally less dense and cheaper, often used in plywood and furniture.
- Examples: Cedar, Douglas fir, pine, spruce.
- Hardwoods are denser, more durable, and more expensive, used especially for furniture and building materials.
- Examples: Poplar, ash, maple, oak, teak.
- Density measures material mass per unit volume.
- Aluminum and magnesium are typically less dense, while others like titanium, gold, steel, tungsten, lead, and platinum are denser.
Additional Specifics
- Wood veneers are thin wood slices, used for aesthetic purposes on cheaper wood products.
- Concrete is a foundational material for constructing buildings.
- Framing lumber is utilized for constructing building frame structures.
- Plywood offers good water resistance, used in roof coverings.
- Most modern home construction uses dimensional lumber alongside concrete and plywood.
- Specific strength calculates strength-to-weight ratios of materials.
- Carbon fiber is a strong, light material used in high-performance applications like bulletproof vests.
- Alloys combine two or more metals to create new properties.
- Rust's chemical composition is a common oxidation reaction on iron and steel.
- Material hardness is measured by resistance to plastic deformation or changes in shape.
- Toughening/hardening processes like quenching affect material hardness properties.
- Sintering is a manufacturing process for combining metal powders or other materials.
- Ferrous metals contain iron and are often magnetic.
- Most plastics derive from hydrocarbon molecules from fossil fuels (crude oil, natural gas, coal).
- Thermoplastics can be reshaped by heating/cooling cycles.
Lab Safety
- OSHA (Occupational Safety & Health Administration) mandates safety standards.
- Use appropriate attire.
- Alert supervisors of injuries or near misses
- Wear safety glasses and appropriate PPE while working with power tools.
- Maintain a safe distance when interacting.
- Follow all safety procedures when working with power tools.
Engineering Drawings
- Engineers use notebooks for detailed records of work.
- Sketches include labelled components using isometric projection views for 3D representation.
- Scale factors are often used to show relative sizing proportional to actual dimensions.
- Engineering drawings show various view perspectives: top, front, side, and section views, etc.
Fundamentals of Aerospace
- Airfoil design relies on Bernoulli's Principle for lift.
- Higher airspeed over the top of an airfoil creates lower pressure than the bottom.
Fundamentals of Manufacturing
- Coordinates specify locations in 3D space for geometric shapes and objects.
- Absolute coordinates define a point's location based on a reference origin (0,0).
- Coordinate systems are used in coordinate programming (as well as CAM) software.
Fundamentals of Robotics
- Robotic arms have components like wrist (two degrees of freedom), elbow, shoulder, and body joints
- Microcontrollers control the robotic arm's functionality.
- Motor controllers vary motors' speeds and actions.
Fundamentals of Electrical
- Circuit components are shown by standard symbols.
- Electrical schematics do not show accurate dimensions.
- Electrical circuits have voltage and current characteristics that are dependent on individual component configuration.
- Series circuit characteristic: total circuit current is the same through all components.
- Parallel circuit characteristic: individual component voltage drops sum to equal the supply voltage.
- Ohm's Law describes characteristics of voltage, current, and resistance.
Other
- The first mass-produced automobile in the U.S. was the 1901 Curved Dash Oldsmobile.
- Quality Control (QC) is a process to maintain or improve product quality by testing and training personnel
- Different forms of energy transformations exist (kinetic to potential)
