Engineering - Design - Architecture

Engineering is the discipline dealing with the art or science of applying scientific knowledge to practical problems. Plan and direct a complex undertaking. Someone who can correctly calculate the load capacities of materials and assemble them correctly.
Engineering is the application of mathematics, empirical evidence and scientific, economic, social, and practical knowledge in order to invent, innovate, design, build, maintain, research, and improve structures, machines, tools, systems, components, materials, and processes. The discipline of engineering is extremely broad, and encompasses a range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied science, technology and types of application.

What Math Skills Are Needed to Become an Engineer?

Basic Arithmetic

All math is based on the idea that 1 plus 1 equals 2, and 1 minus 1 equals 0. Multiplication and division --2 times 2 and 4 divided by 2 -- are variations used to avoid multiple iterations of either subtraction or addition. One example of an engineer's use of basic arithmetic is the civil engineer's calculations for describing water flow across an open basin. The flow is reckoned in cubic feet per second, or Q, where Q equals the runoff coefficient times the intensity of the rain for a specified period, times the area of the basin. If the runoff coefficient is 2, the intensity, in inches of rain, is 4 and the basin -- a specified area of land -- is 1/2 acre, the engineer's formula resembles this: (2x4)/(.5x43,560), or 8/21,780. The result, 0.0003673, is the volume of water, in cubic feet per second, flowing across the land.    Math Knowledge    Next Generation Science Standards
Algebra and Geometry
When several of the factors of a problem are known and one or more are unknown, engineers use Algebra, including differential equations in cases when there are several unknowns. Because engineers work to arrive at a solution to a physical problem, Geometry -- with its planes, circles and angles -- determines such diverse things as the torque used to turn a wheel, and reduces the design of a roadway's curve to an accurate engineering or construction drawing.   
Trigonometry is the science of measuring triangles. Engineers may use plane trigonometry to determine the size of an irregularly shaped parcel of land. It may also be used or to determine the height of an object based solely on the distance to the object and the angle, up or down, from the observer. Spherical trigonometry is used by naval engineers in ship design and by mechanical engineers working on such arcane projects as the design of mechanical hand for an underwater robot.
We all love statistics. They tell us where we stand in the world, among our peers and even in our family. They tell us who's winning. The engineer uses them for the same reasons -- by statistical analysis of the design, the engineer can tell what percentage of a design will need armor or reinforcement or where any likely failures will occur. For the civil engineer, statistics appear as the concentration of rainfall, wind loads and bridge design. In many locations, engineers designing drainage systems must design for a 50- or 100-year storm in their calculations, a significant change from the normal rain concentration.
Calculus is used by engineers to determine rates of change or rates by which factors, such as acceleration or weight, change. It might tell NASA scientists at what point the change in a satellite's orbit will cause the satellite to strike an object in space. A more mundane task for calculus might be determining how large a box must be to accommodate a specific number of things. An engineer who designs packaging, for example, might know that a product of a certain weight must be packaged in groups of no more than 10 because of their weight. Using calculus, he can calculate both the optimum number of objects per box, plus the optimum size of the box.

Building Codes - Rules for Building

Building Code is a set of rules that specify the standards for constructed objects such as buildings and nonbuilding structures. The main purpose of building codes is to protect public health, safety and general welfare as they relate to the construction and occupancy of buildings and structures. The building code becomes law of a particular jurisdiction when formally enacted by the appropriate governmental or private authority. City Development - Surveying
Zoning describes the control by authority which designates legal areas in a municipality to permit and prohibit land uses. Zoning may specify a variety of outright and conditional uses of land. It may also indicate the size and dimensions of land area as well as the form and scale of buildings. These guidelines are set in order to guide urban growth and development

Wally Wallington from Flint Michigan has demonstrated that he can lift a Stonehenge-sized pillar weighing 22,000 lbs and moved a barn over 300 ft. What makes this so special is that he does it using only himself, gravity, and his incredible ingenuity.
Leverage is a force compounded by means of a lever rotating around a pivot, which is the point of rotation in a lever system; Torque. A Lever is a machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum, which is the support about which a lever pivots. A lever is a rigid body capable of rotating on a point on itself. On the basis of the location of fulcrum, load and effort, the lever is divided into three types. It is one of the six simple machines identified by Renaissance scientists. A lever amplifies an input force to provide a greater output force, which is said to provide leverage. The ratio of the output force to the input force is the mechanical advantage of the lever. Mechanical Advantage is the ratio of the output force produced by a machine (especially a simple machine) to the applied input force.

Scaffolding is a temporary structure used to support a work crew and materials to aid in the construction, maintenance and repair of buildings, bridges and all other man made structures. Scaffolding is also used in adapted forms for formwork and shoring, grandstand seating, concert stages, access/viewing towers, exhibition stands, ski ramps, half pipes and art projects.

Wood Working

"Measure twice, cut once"

Wood Working Carpentry is a skilled trade in which the primary work performed is the cutting, shaping and installation of building materials during the construction of buildings, ships, timber bridges, concrete formwork, etc. Carpenters traditionally worked with natural wood and did the rougher work such as framing, but today many other materials are also used and sometimes the finer trades of cabinetmaking and furniture building are considered carpentry.
Joinery involves joining together pieces of timber or lumber, to produce more complex items. Some wood joints employ fasteners, bindings, or adhesives, while others use only wood elements. The characteristics of wooden joints - strength, flexibility, toughness, appearance, etc. - derive from the properties of the materials involved and the purpose of the joint. Therefore, different joinery techniques are used to meet differing requirements. For example, the joinery used to construct a house can be different from that used to make puzzle toys, although some concepts overlap.
Woodworking is the activity or skill of making items from wood, and includes cabinet making (Cabinetry and Furniture), wood carving, joinery, and carpentry.

Mechanization is the process of changing from working largely or exclusively by hand or with animals to doing that work with machinery. Every machine is constructed for the purpose of performing certain mechanical operations, each of which supposes the existence of two other things besides the machine in question, namely, a moving power, and an object subject to the operation, which may be termed the work to be done. Machines, in fact, are interposed between the power and the work, for the purpose of adapting the one to the other.

Machine to Machine refers to direct communication between devices using any communications channel, including wired and wireless. Machine to machine communication can include industrial instrumentation, enabling a sensor or meter to communicate the data it records (such as temperature, inventory level, etc.) to application software that can use it (for example, adjusting an industrial process based on temperature or placing orders to replenish inventory). Such communication was originally accomplished by having a remote network of machines relay information back to a central hub for analysis, which would then be rerouted into a system like a personal computer

Multiaxis Machining is a manufacturing process where computer numerically controlled tools that move in 4 or more ways are used to manufacture parts out of metal or other materials by milling away excess material, by water jet cutting or by laser cutting. Typical CNC tools support translation in 3 axis; multiaxis machines also support rotation around one or multiple axis. There are now many CAM (computer aided manufacturing) software systems available to support multiaxis machining including software that can automatically convert 3-axis toolpaths into 5-axis toolpaths. Five-axis machine tools are known to have 41 basic geometric errors,The way you want the machine to move (when making a large part) is different than the way it actually moves due to inherent geometric errors." Because of these errors, manufacturers must make adjustments in calibrating their CNC machines. Researchers develop ways to improve machining, milling processes

Machining is any of various processes in which a piece of raw material is cut into a desired final shape and size by a controlled material-removal process. The processes that have this common theme, controlled material removal, are today collectively known as subtractive manufacturing, in distinction from processes of controlled material addition, which are known as additive manufacturing. Exactly what the "controlled" part of the definition implies can vary, but it almost always implies the use of machine tools (in addition to just power tools and hand tools).

Measuring Tools
Measuring Tools Ruler is an instrument used in geometry, technical drawing, printing, engineering and building to measure distances or to rule straight lines. The ruler is a straightedge which may also contain calibrated lines to measure distances.
Steel Square is a long-armed square that has additional uses for measurement, especially of angles, as well as simple right-angles. Today the steel square is more commonly referred to as the framing square. It consists of a long arm and a shorter one, which meet at an angle of 90 degrees (a right angle). It can also be made of metals like aluminum, which is light and resistant to rust.
Protractor is for measuring angles. Most protractors measure angles in degrees (°). Radian-scale protractors measure angles in radians. Most protractors are divided into 180 equal parts.
Gauge is a device used to make measurements or in order to display certain information, like time.
Micrometer is a device incorporating a calibrated screw widely used for precise measurement of components in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers.
