T11.2 Securing Fasteners

T11.2.1 All critical bolt, nuts, and other fasteners on the steering, braking, driver’s harness, and suspension

must be secured from unintentional loosening by the use of positive locking mechanisms. Positive locking mechanisms include:

· Correctly installed safety wiring

· Cotter pins

· Nylon lock nuts

· Prevailing torque lock nuts

Note: Lock washers and thread locking compounds, e.g. Loctite®, DO NOT meet the positive locking requirement.

T11.2.2 There must be a minimum of two (2) full threads projecting from any lock nut.

T11.2.3 All spherical rod ends and spherical bearings on the steering or suspension must be in double shear or captured by having a screw/bolt head or washer with an O.D. that is larger than spherical bearing housing I.D.

T11.2.4 Adjustable tie-rod ends must be constrained with a jam nut to prevent loosening.

ARTICLE 12: TRANSPONDERS

T12.1 Transponders – North American FSAE Competitions

T12.1.1 Transponders will be used as part of the timing system for the dynamic events at the North American

FSAE competitions

T12.1.2 Each team is responsible for having a functional, properly mounted transponder of the specified type on their vehicle. Vehicles without a specified transponder will not be allowed to compete in any event for which a transponder is used for timing and scoring.

T12.1.3 All vehicles must be equipped with at least one MYLAPS Car/Bike Rechargeable Power Transponder or MYLAPS Car/Bike Direct Power Transponder.

Note 1: Except for their name, AMB TranX260 transponders are identical to MYLAPS Car/Bike Transponders and fully comply with this rule. If you own a functional AMB TranX260 it does not need to be replaced.

Note 2: For Electric Vehicles, it is the responsibility of the team to ensure that electrical interference from their vehicle does not stop the transponder from functioning correctly

T12.2 Transponders – Events outside North America

Transponders may be used for timing and scoring at competitions outside North America and may be

provided by the competition organizers. The transponders specified in T12.1 above for the North

American FSAE competitions may or may not be compatible with the systems used for other events. Teams should check the individual competition websites for further details.

T12.3 Transponder Mounting – All Events

The transponder mounting requirements are:

a. Orientation – The transponder must be mounted vertically and orientated so the number can be

read “right-side up”.

b. Location – The transponder must be mounted on the driver’s right side of the car forward of the

front roll hoop. The transponder must be no more than 60 cm (24 in) above the track.

c. Obstructions – There must be an open, unobstructed line between the antenna on the bottom of the transponder and the ground. Metal and carbon fiber may interrupt the transponder signal. The

signal will normally transmit through fiberglass and plastic. If the signal will be obstructed by

metal or carbon fiber, a 10.2 cm (4 in) diameter opening can be cut, the transponder mounted flush with the opening, and the opening covered with a material transparent to the signal.

d. Protection – Mount the transponder where it will be protected from obstacles.

ARTICLE 13: VEHICLE IDENTIFICATION T13.1 Car Number

T13.1.1 Each car will be assigned a number at the time of its entry into a competition.

T13.1.2 Car numbers must appear on the vehicle as follows: Locations: In three (3) locations: the front and both sides;

a. Height: At least 152.4 mm (6 inch) high;

b. Font: Block numbers (i.e. sans-serif characters). Italic, outline, serif, shadow, or cursive numbers are prohibited.

c. Stroke Width and Spacing between Numbers: At least 18 mm (3/4 inch).

d. Color: Either white numbers on a black background or black numbers on a white background. No other color combinations will be approved.

e. Background shape: The number background must be one of the following: round, oval, square or rectangular. There must be at least 25.4 mm (1 inch) between the edge of the numbers and the edge of the background.

f. Clear: The numbers must not be obscured by parts of the car, e.g. wheels, side pods, exhaust system, etc.

T13.1.3 Car numbers for teams registered for North American FSAE competitions can be found on the

“Registered Teams” section of the relevant Formula SAE website.

Comment: Car numbers must be quickly read by course marshals when your car is moving at speed. Make your numbers easy to see and easy to read.
