Aerodynamics / Suspension
The force produced by the car that resists forward movement.
What is drag?
The ratio of braking force on the front wheels vs the rear wheels.
What is brake bias (brake balance)?
A metal template used to represent the 95th percentile male and 5th percentile female.
What is Percy?
The drivetrain setup (system used to redirect the rotational motion from the engine to the rear axle) that was used on Murphy and is planned for this year's car.
What is a spool / chain drive?
The components that support and connect the knuckles (wheels) to the chassis and determines the motion path of the wheels during dynamic loading events.
What are control arms?
A safety gate for current used to protect electrical components.
What is a fuse?
The material selection for the chassis of WR 9 and Murphy.
What is 4130 steel (chromoly)?
This term is used to describe an engine's ability to move at certain amount of weight at a certain rate. It's often confused with the related term that describes the engine's ability to move a certain amount of weight.
What is horsepower?
The force produced by the car that pushes it into the track.
What is downforce?
A component that converts the force placed on the brake pedal into brake pressure in the brake lines.
What is a master cylinder?
The three technical inspection tests used for cockpit to ensure driver safety and accessibility.
What is the broomstick test, the template test, and the driver egress test?
A mathematical model (presented in tables and/or 3-dimensional surfaces) representing information from sensors on the engine and is used to control fuel delivery and engine timing.
What is an engine tune?
A point in space that represents the average location of the force applied over an area of a body.
What is the center of pressure?
An electrical component that allows small current circuits to “trigger” / operate larger current circuits or components.
What is a relay?
An aspect of design for space-frame chasses that uses geometry to strengthen and support adjacent members. Use of this method is required by the SES for structural members.
What is triangulation?
A type of drivetrain that allows two wheels powered by the engine to rotate at different speeds in cornering.
What is a differential?
A mathematical model used to determine the output forces of a tire given the input forces.
What is a tire model?
In a brake system, _____ are used to transfer braking force from the system to the wheels where making a connection is difficult. However, using this decreases the efficiency of braking due to energy loss.
What are soft lines?
The amount the chassis deflects when a torsional load is applied.
What is torsional stiffness?
A component used to control the air/fuel mixture that is not dependent on a pump or electronic sensors.
What is a carburetor?
