mechanism Its made up of several different types of machines that work together to perform a specific task.
Simple Machine Its a machine that needs force to function.
Lever its a bar that is supported at a pivot point.
fulcrum its where a lever rests.
pulley Its a Wheel that that has a rope or a cable looped around it.
Inclined Plane Its basically a larger wedge, it's used by lifting items.
screw Its an inclined plane wrapped around a rod
Wedge Its an inclined Plane that travels through an object
efficiency the blank of a machine measures the useful work done by the machine compared to the work needed to operated
wheel and axel it consists of a shaft that is attached to a larger disk
automated system It's a system that's made to perform a task on its own with little to no human interference.
non-mechanical systems it includes procedures, processes, and people needed to perform a task.
quantitative assessment involves analysis of numerical data
productivity amount of output that is produced per unit of time.
criteria its basically a rubric of sorts.
first type of criteria..efficiency effeciency, they monitor the efficiency of a system of sorts.
second type of criteria..cost cost, they monitor the price/cost a system takes.
third type of criteria..safety safety, they monitor how safe a system is.
fourth type of criteria..environmental impact environmental impact, they monitor the impact the system would do to the environment.
formula for work equals force X distance.
work input ideally equals work output.
mechanical advantage formula equals force output/force input.
ideal mechanical advantage forula equals distance input/distance output.
efficiency formula Useful output work/ input work X 100 for percentage
components pieces of a system that need to interact to function.
consumer an individual that uses the goods or services provided by a system.
mass production it's the production of large amounts of a product type by an automated mechanical process.
qualitative assessment its an assessment made by observations ex, my art got a good rating.
useful output work the energy that is effectively passed on or used by a device or system, excluding any energy that is wasted or lost as heat
societal needs the essential requirements and interests of a community or society.
product manual its a document that teaches users how to succesfully use it
useful output work formula Dout x Fout
lever IMA length of input arm /length of output arm
wedge & inclined plane IMA length of ramp/height of ramp
screw IMA Din/Dout
pulley IMA number of segments
wheel and axel IMA radius of wheel/radius of axel
all types of criteria efficiency, cost, safety, environmental impact.
