Gearling — Levers Lever Lift Yard
Hi!
I'm Gearling.
Welcome to Lever Lift Yard!
Will you help me investigate levers?
The Grumblies have mixed up our clues.
Let's check the evidence!
A lever is a rigid part turning about a fulcrum.
The effort is the applied force;
the load is what it acts on.
What is the fulcrum?
- A. The load's color
- B. The effort's name
- C. The pivot
The answer is C: The pivot
A lever is a rigid part turning about a fulcrum.
The effort is the applied force;
the load is what it acts on.
That clue helps us make sense of this place.
Changing the arrangement changes the force and distance tradeoff.
Moving the effort farther from the fulcrum can reduce the
force needed for a given load in an ideal model.
What is the effort?
- A. Only the pivot
- B. The applied force
- C. Only the object being lifted
The answer is B: The applied force
A lever is a rigid part turning about a fulcrum.
The effort is the applied force;
the load is what it acts on.
Hmm...
how does that connect to our first clue?
Our record keeps the load near the fulcrum
and applies effort farther away.
The setup lifts the model load with a smaller effort force
but a larger effort movement.
Which arrangement fits the supplied result?
- A. Effort farther from the pivot than the load
- B. Effort always at the pivot
- C. Both effort and load exactly at the pivot
The answer is A: Effort farther from the pivot than the load
Changing the arrangement changes the force and distance tradeoff.
Moving the effort farther from the fulcrum can reduce the
force needed for a given load in an ideal model.
Nice investigating!
