Mechanical Systems & Circuits
The code run continuously, where sensor reading + decision-making + motor control happens, over and over
What is loop()?
What is FF= μN?
The power source of a car
What is the engine?
A push or pull that acts on an object as a result of that object's interaction with its surroundings
What is a force?
A student is connecting their wires between the breadboard and Arduino, while it is plugged into the laptop. Facilitators should..
What is reviewing safety basics with the students and monitoring closely during this activity?
A closed loop path allowing electricity to flow from a power source, through conductors and components, back to the source
What is a basic circuit?
The difference between the normal and subscript F's in the formula
What is a Force and type of force?
The smoothest path through a turn, usually entering wide
What is the racing line?
Requires two objects to be touching; ex. the tire pushing on the track
What are contact forces?
Waymo uses laser-based sensing to map its surroundings
What is LIDAR (Light Detection and Ranging)?
You are entering the freeway, approaching 60 MPH, you must shift into the ___ gear
What is the 4th gear?
In the formula, higher μ or higher N represents
What is more grip or more weight pressing down, causing more friction force?
Where a driver starts slowing down before a turn
What is the braking point?
You are driving on the freeway and all of a sudden you hit the brakes, causing the car to decelerate.
What is a net force backward?
You are at a full stop and traffic isn't moving, you are in ___ gear
What is Neutral?
If your wheels were locked together and had to spin at the exact same speed, your car would fight itself every time it turned
What is missing a differential?
You are drifting through a turn; connect your observations to the formula FF= μN
What is lower μ caused by the surface, producing greater FF, resulting in loss of static traction and drift?
The fastest section of a track where there is full acceleration
What are the straights in a track?
You are driving the car and as you hit the gas, the car accelerates
What is an unbalanced net force?
You are oversteering at a turn, causing the back of the car to swing out more than intended, you must..
What is steering into the skid and gradually easing off the gas (power)?
The conversion of engine power into usable speed/torque through a set of gears
What is a transmission?
You rapidly accelerate from a stop, connect your observations to the formula FF=μN
What is a higher μ, giving the tires more traction and allowing the car to accelerate more efficiently?
The tightest point of a turn during a race
You are approaching a green arrow at a stoplight, you decelerate and begin steering right.
What is a sideways net force?
You are understeering at a turn, causing the car to continue straight or drift wide, you must..
