MCAS Review: Technology and Engineering
Terms in this set (68)
the resistance of the airplane to forward motion- It works against thrust and is caused by the resistance of air
the force caused by the engine or propeller- It pushes the air backward and moves the vehicle in the forward direction
upward force created by the wings moving through the air- works perpendicular to thrust
force due to two objects rubbing against each other
downward force due to the weight of the vehicle
Controls speed and direction of a vehicle
a system of equipment for guiding the path of a vehicle
provides structural support for all the other vehicle components, and holds them in position
provides the energy to move a vehicle; this can be an internal combustion engine, an electric motor, or rocket engine
a mechanical system of springs or shock absorbers connecting the wheels and axles to the body of a wheeled vehicle
force that stretches and pulls apart
force that pushes in opposite directions within the material
flat beam that is supported by two piers
large abutments at the end of the bridge with an arch shape in the middle
bridge that hangs between two tower-like structures with cables
any finish material applied over a floor structure to provide a walking surface
Used usually to keep in heat or air conditioned air
Outside of your house to protect it from the weather and for decoration
Supports weight and provide a flat and level base for construction
Provides a stable frame to which interior and exterior wall coverings are attached
System of pipes and drains installed in a building for moving water and the removal of wastes
Something put into a system, such as resources, in order to achieve a result.
the steps needed to complete a series of identifiable tasks within a system
an objective that a person or piece of technology wants to obtain and works to achieve
the process in which the results of the output of a system are used to modify or input the input
universal systems model
everything has a system or is made of a system including input, process and output
Tools that hold
Tools that separate
hammer, pliers, band saw, drill press, sander
Tools that fasten
hammer, pliers, wrench, nuts and bolts, nails, screws, screwdriver
Tools that lift
incline plane, pulley, car jack
natural material from trees that is strong, but lacks waterproof and flexibility properties
natural material from trees that is flexible, but not strong or waterproof
usually in a liquid state, that adheres or bonds items together. Adhesives come from either natural or man-made sources
used to dissolve adhesives, or break bonds
sand, gravel, crushed stone, or recycled concrete that are put into composite materials such as concrete and asphalt concrete. Adds strength to the overall composite material.
moldable, man-made material that its lightweight, inexpensive, and can easily be made transparent.
are a good conductor of both electricity and heat. Metals are usually malleable and shiny.
comes from the word pottery, often found in porcelain, china, bricks, plates, etc
steps of the engineering/design process
1) Identify the need or problem
2) Research the problem
3) Develop possible solutions
4) Select the best possible solution(s)
5) Construct a prototype
6) Test and evaluate
7) Communicate the solution(s)
a 2-D, or flat, representation of a 3-D object using views of each side of the object.
consists of two or more views of a 3D object
the process of changing raw materials into physical goods, involving multiple industrial processes. It can be created in one of two ways...
the creation of a limited number of items at a high cost that requires one or two people with a special skill to create a product (ex. your grandma knitting you a sweater).
allows for the manufacturing of the same item many times. It is much faster and cheaper that custom making an object. Mass production often uses interchangeable parts to make production faster.
a part of a product that can easily be replaced and used in other area of the product so that it can be quickly fixed.
Research and development
works with marketing to create an idea for the product
develops a plan and mass-produces the product
determines what types of products should be made and makes sure that the company understands what the consumer wants and needs.
during product they are responsible for making sure it meets appropriate standards
transports the product to the consumers
breaking the physical bonds of a material, using blades, blowtorches, or lasers
changing the shape of a piece to fit the final structure, often by pouring a liquid into a mold
putting the various components together in the correct order
gluing, welding, bolting, strengthening the bonds
treating the product to improve its performance and/or appearance
overseeing all steps in the process to ensure maximum quality
training operators and designing workspaces to increase safety
is a device, or person that sends information
an object which turns message data and sounds into codes that can be sent
converts electrical currents into radio waves, which are then sent out over an antenna
the part of a radio that receives radio waves from the antenna and converts them into electrical currents
is a device which does the reverse of an encoder, undoing the encoding so that the original information can be retrieved
often called memory, refers to computer components and recording media that keep digital data
The process of accessing information from memory or other storage devices
the receiver of the information
