Simple Machines
How do you calculate mechanical advantage?
Ratio of output force to input force
What is the formula to calculate work?
Force x Displacement
How do you calculate mechanical advantage for a gear ratio?
Ratio of the number of teeth on each gear. Driving gear goes first.
(Traditional Jeopardy Question) A tool that creates a 2D drawing.
What is the sketch tool?
(Traditional Jeopardy Question) An Italian open-source hardware and software company.
What is Arduino?
(Traditional Jeopardy Question) A simple machine whose output force is perpendicular to its input force.
What is a wedge?
Is static friction or kinetic friction easier to overcome?
kinetic friction
What is this Gear Ratio? (Smaller gear is the driving gear)
7:1
(Traditional Jeopardy Question) Reflects a sketch across a line of symmetry.
What is the mirror tool?
Is the longer leg of an LED the anode or the cathode?
The anode.
What is the mechanical advantage produced in the following image?
IMA = 4
How do Catapults work?
Catapults transfer elastic potential energy into kinetic energy to fire the load.
If there are two gears in a gear system and the larger gear is driving, is the system geared for speed or strength?
Speed
(Traditional Jeopardy Question) Makes multiple copies of a sketch or entity and arranges them into a circular or rectangular pattern
What is Linear or Circular Pattern?
What do you need to code to set and LED as an output in the setup function?
pinMode(led, OUTPUT) (assuming you have named a variable LED and already assigned a digital pin to it)
(Traditional Jeopardy Question) Essentially an incline wrapped around a pole.
What is a screw?
(Traditional Jeopardy Question) A type of energy that consists of changing magnetic and electric fields.
What is Electromagnetic energy?
What is this gear ratio? (largest gear is driving)
1:56
(Traditional Jeopardy Question) Makes a sketch entity coincident with an entity that is outside of the sketch.
What is the pierce tool?
Do you assign potentiometers using digital or analog pins?
Analog (you can control them using digital pins, but you get a much larger range of output and input values with analog pins)
