Questions and Answers
  • 1. 

    What is the minimum ground clearance required for the kart?

    • A. 

      1" without driver aboard

    • B. 

      2" without driver aboard

    • C. 

      2" with driver aboard

    • D. 

      1" with driver aboard

    Correct Answer
    D. 1" with driver aboard
    Explanation
    The minimum ground clearance required for the kart is 1" with the driver aboard. This means that there should be at least a 1-inch gap between the bottom of the kart and the ground when the driver is seated in it. This is important for ensuring that the kart can navigate smoothly over uneven terrain without scraping or getting stuck.

    Maximum permissible weight of the EV kart (without driver)?

    • A. 

      120kg

    • B. 

      115kg

    • C. 

      150kg

    • D. 

      160kg

    Correct Answer
    C. 150kg
    Explanation
    The maximum permissible weight of the EV kart (without driver) is 150kg. This means that the kart can weigh up to 150kg without the driver's weight included.

  • 4. 

    Minimum number of kill switches required on the Kart?

    • A. 

      2

    • B. 

      1

    • C. 

      0

    • D. 

      3

    Correct Answer
    A. 2
    Explanation
    The minimum number of kill switches required on the Kart is 2. This means that there should be at least 2 kill switches installed on the Kart for safety purposes. These kill switches are designed to quickly shut off the engine in case of an emergency or if the driver loses control of the vehicle. Having multiple kill switches ensures that there is a backup option available in case one of the switches fails or becomes inaccessible.

  • 5. 

    Minimum number and type of fire extinguisher required with the team for the event?

    • A. 

      2x1kg CO2 extinguishers

    • B. 

      1x1kg CO2 and 1x1kg ABC extinguishers

    • C. 

      2x1kg ABC extinguishers

    • D. 

      1x2kg ABC extinguisher

    Correct Answer
    C. 2x1kg ABC extinguishers
    Explanation
    The correct answer is 2x1kg ABC extinguishers. This is because ABC extinguishers are versatile and can be used to extinguish fires caused by different types of materials, including ordinary combustibles (Class A), flammable liquids (Class B), and electrical equipment (Class C). Having two extinguishers ensures that there is enough firefighting capability to handle multiple fires or a larger fire. The 1kg size is suitable for small fires and is easy to handle. CO2 extinguishers are not necessary unless there is a specific risk of fires caused by electrical equipment.

    Rate this question:

  • 6. 

    Which of the following statements are true regarding the event's definition for the term "firewall"? a) Firewall may have holes for ventillation. b) It is a boundary which protects the driver from the heat/fire produced by the engine/motor/battery/exhaust. c) It must fulfill its purpose during both static and dynamic conditions of the vehicle. d) It may be made of 2mm thick sheets of Acrylic or Plastic.

    • A. 

      A,b,c only

    • B. 

      B,c,d only

    • C. 

      A & d only

    • D. 

      B & c only

    Correct Answer
    D. B & c only
    Explanation
    The correct answer is b & c only. This is because statement b states that a firewall is a boundary that protects the driver from the heat/fire produced by the engine/motor/battery/exhaust, which aligns with the definition of a firewall in the context of a vehicle. Statement c states that the firewall must fulfill its purpose during both static and dynamic conditions of the vehicle, which is also true for a firewall. Statements a and d are not true because statement a refers to holes for ventilation, which is not a characteristic of a firewall, and statement d mentions the material of the firewall, which is not specified in the given definition.

    Maximum voltage and power rating permitted for the Electric Tractive system (respectively)?

    • A. 

      24V, 6kW

    • B. 

      72V, 6kW

    • C. 

      6V, 72kW

    • D. 

      24V, 12kW

    • E. 

      12V, 12kW

    Correct Answer
    B. 72V, 6kW
    Explanation
    The maximum voltage and power rating permitted for the Electric Tractive system is 72V and 6kW respectively.

    Full form of AIR(s) used in the Electric Tractive system:

    • A. 

      Accumulator Induction Relay

    • B. 

      Accumulator Induction Rectifier

    • C. 

      Accumulator Isolation Regulator

    • D. 

      Accumulator Isolation Relay

    • E. 

      Accumulator Insulation Regulator

    Correct Answer
    D. Accumulator Isolation Relay
    Explanation
    The correct answer is Accumulator Isolation Relay. In an electric tractive system, an accumulator is a device that stores energy from regenerative braking or other sources. Isolation refers to the separation of electrical circuits to prevent unwanted interactions. A relay is an electrical switch that controls the flow of current in a circuit. Therefore, an accumulator isolation relay would be a component in the system that controls the isolation of the accumulator from other circuits.

    Correct Answer(s)
    A. Lead-Acid batteries
    B. Ni-Cd batteries
    C. Li-ion batteries
    E. Supercapacitors
    Explanation
    The Tractive System Accumulator(s) allowed for the event include Lead-Acid batteries, Ni-Cd batteries, Li-ion batteries, and Supercapacitors. These are all types of energy storage systems commonly used in various applications, including electric vehicles. Fuel Cells and Thermal batteries are not included in the allowed options. Li-Cl (Molten salt) batteries are not mentioned in the given options, so it is unclear whether they are allowed or not.

  • 10. 

    Which of the following statements are true regarding BLDC motors: a) They are DC powered and converted to AC waveform for operation. b) They are AC powered and converted to DC waveform for operation. c) They are synchronous motors. d) They have brushes for commutator function.

    • A. 

      B and c only

    • B. 

      B, c and d only

    • C. 

      A and c only

    • D. 

      A,c and d only

    Correct Answer
    C. A and c only
    Explanation
    BLDC motors are not DC powered and converted to AC waveform for operation, so statement a) is false. However, they are synchronous motors, so statement c) is true. Therefore, the correct answer is a and c only.

    Rate this question:

  • 11. 

    For constant power output on a rotating body, how are torque and rpm of the body related?

    • A. 

      Torque increases as Rpm increases

    • B. 

      Torque decreases as Rpm increases

    • C. 

      Torque remains the same when Rpm increases

    • D. 

      Torque and Rpm are always constant and cannot be changed.

    Correct Answer
    B. Torque decreases as Rpm increases
    Explanation
    For a constant power output on a rotating body, the relationship between torque and rpm is inversely proportional. As the rpm increases, the torque decreases. This is because torque is the rotational force required to produce the desired power output, and as the rotational speed increases, less torque is needed to maintain the same power output. Conversely, if the rpm decreases, more torque is required to maintain the same power output.
