Modification NOT permitted to the vehicle after approval to compete in dynamic events :
Correct Answer
A. Adjustment of wing location
Explanation
The adjustment of wing location is not permitted after approval to compete in dynamic events. This means that once the vehicle has been approved, any modifications or adjustments to the wing location are not allowed. This could be due to safety concerns or to maintain a level playing field among competitors. However, adjustments such as tire pressure, pedal assembly, and sway bars are allowed, as they do not involve changing the physical location of any components on the vehicle.
2.

Correct Answer
C. 2.95 in ; 2.95 in
Explanation
The Keep-Out-Zone is defined by two lines extending vertically from positions 2.95 in in front of and 2.95 in behind, the outer diameter of the wheel.
3.
Outer circle radius of skid pad layout is ..........
Correct Answer
D. 34.86 ft
Explanation

4.
The minimum field of vision (in degrees) and maximum egress time (in sec) allowable for a driver are respectively:
Correct Answer
B. 200 , 5
Explanation
The correct answer is 200, 5. This means that the minimum field of vision for a driver is 200 degrees, allowing them to have a wider range of vision. The maximum egress time is 5 seconds, which means that the driver should be able to exit a vehicle within this time frame in case of an emergency.
5.

Correct Answer
B. 25.4 , 50.8
Explanation
The minimum allowable jounce and wheel travel for a fully operational suspension system with the driver seated is 25.4mm for jounce and 50.8mm for wheel travel.
6.
Which of the following does NOT meet the positive locking requirement?
Correct Answer
D. Bolts with nylon patches
Explanation
Bolts with nylon patches do not meet the positive locking requirement because the nylon patches provide a form of self-locking mechanism. The nylon patches create friction between the bolt and the mating surface, preventing the bolt from loosening due to vibrations or other external forces. This ensures that the bolt remains securely fastened in place. Therefore, bolts with nylon patches do not require additional locking mechanisms such as safety wiring, cotter pins, or prevailing torque lock nuts.
7.
Which of the following is WRONG regarding GLV (Grounded Low Voltage) ?
Correct Answer
C. The GLV system must be completely isolated from the chassis.
Explanation
The GLV system must be completely isolated from the chassis. This statement is incorrect because the GLV system is actually connected to the chassis for grounding purposes. The chassis acts as a return path for electrical current in the GLV system, ensuring that any stray current is safely directed away from the vehicle. Therefore, the GLV system is not completely isolated from the chassis.
8.
The allowable thickness of structural casing of rotating part of motor is
Correct Answer
C. Minimum 0.080 inch for steel
Explanation
The given answer is "Minimum 0.080 inch for steel." This means that the minimum allowable thickness for the structural casing of the rotating part of the motor is 0.080 inch if it is made of steel.
9.
A minimum of 8 fasteners are required to attach accumulator container to the major structure of chassis by 8mm Metric Grade 8.8 fasteners, or stronger for accumulators weighing .........
Correct Answer
C. More than 30 kg and less than 40 kg
Explanation
The correct answer is "more than 30 kg and less than 40 kg". This is because the question states that a minimum of 8 fasteners are required to attach the accumulator container to the major structure of the chassis, and specifies that 8mm Metric Grade 8.8 fasteners, or stronger, should be used. This implies that the weight of the accumulator container must be within a certain range to require this number and strength of fasteners. The only option that falls within this range is "more than 30 kg and less than 40 kg".
10.
For EV vehicles the correct order of tests during vehicle inspection is
Correct Answer
C. Ready-To-Drive-Sound Test--> Rain test-->Brake test
Explanation
The correct order of tests for EV vehicles during vehicle inspection is the Ready-To-Drive-Sound Test, followed by the Rain test, and then the Brake test. This order ensures that the vehicle's sound system is functioning properly before testing its performance in wet conditions and finally assessing its braking capabilities.
