Simple Machines
IMA, AMA and Efficency
Airplanes
Other
100
This is the first step
What is Identify the problem
100
This is the simple machine that almost everyone thinks of because all vehicles have it.
What is Wheel and Axel
100
What is the IMA of a ramp 5 meters high and 25 meters long?
What is 5 meters
100
Produce lift so the plane can get up into the sky
What do wings do?
100
this generates thrust to push the plane through the air.
What is the turbine engines
200
This is the second step
What is Research the problem
200
This simple machine is best for raising something heavier than you can carry
What is a pulley
200
This is what AMA stands for
What is Actual Mechanical Advantage
200
Helps control movement to the right and left. keeps the plane stable.
What is the rudder?
200
What is the 6th step of the engineering design cycle
What is test and evaluate
300
There are ________________ steps
The engineering design process has 8 ______________
300
A screw has what other simple machine incorporated in it
What is a wedge
300
What is the IMA of a pulley with 7 ropes and the last rope is coming off of the top
What is 6
300
moving piece on the back part of the wing that helps the plane take off by increasing lift.
What is a flap
300
What needs to be handed in every two weeks
What is an engineering journal?
400
This is the 5th step
What is Construct a prototype
400
Draw the three classes of levers
What is the fulcrum in different places
400
This is the equation for efficency
What is AMA (weight of object / effort force) / IMA
400
helps the plane descend so the pilot can land the plane
What is a spoiler
400
what concept were we learning when we made catapults
What are simple machines
500
What is the seventh step and most forgotten step
What is Communicate the solution
500
These are the six simple machines
What is lever, wheel and axle, pulley, wedge, incline plane, and screw
500
This is the IMA of a wheel
What is Radius of wheel / radius of axle. or you can use diameters
500
helps control up and down movement of the plane, or pitch, and keeps the plane stable
What is an elevator?
500
When does this class get out?
What is 9:19
