Gearling — How Machines Help Workshop Gate
Hi!
I'm Gearling.
Welcome to Workshop Gate!
Will you help me investigate how machines help?
The Grumblies have mixed up our clues.
Let's check the evidence!
Simple machines help apply forces,
change their direction or trade force for distance.
They do not create energy from nothing.
Do machines create energy from nothing?
- A. No
- B. Yes
- C. Only very large machines do
The answer is A: No
Simple machines help apply forces,
change their direction or trade force for distance.
They do not create energy from nothing.
That clue helps us make sense of this place.
The six traditional types are lever, pulley, wheel and axle, inclined plane,
wedge and screw.
Compound machines combine parts.
What tradeoff can a ramp offer?
- A. Less force and no movement distance
- B. Less energy than nothing
- C. Less force over a longer distance
The answer is C: Less force over a longer distance
Our load model compares lifting straight up with moving along
a longer ramp.
The ramp can reduce the needed pushing force
while increasing the distance moved, under suitable conditions.
Hmm...
how does that connect to our first clue?
Our load model compares lifting straight up with moving along
a longer ramp.
The ramp can reduce the needed pushing force
while increasing the distance moved, under suitable conditions.
Which is a traditional simple machine?
- A. A painted arrow
- B. A lever
- C. A seventh type called a color label
The answer is B: A lever
