Which of the following materials is not considered to be suitable for driver’s suite?
-
PBI
-
Indura
-
Nylon
-
Proban
Correct Answer
A. NylonExplanation
Nylon is not considered to be suitable for a driver's suit because it is not fire-resistant. Driver's suits are designed to protect drivers from fire hazards, and materials like PBI, Indura, and Proban are known for their fire-resistant properties. Nylon, on the other hand, is a synthetic material that is highly flammable and can melt when exposed to heat, making it unsuitable for use in driver's suits.Rate this question:

Your race car (1800mm Wheelbase) has a weight distribution of 64% rear. When seating a 75kg driver, the CoG shifts 144mm forward. What is the weight distribution with driver ?
-
44% front
-
59% rear
-
54% rear
-
49% front
Correct Answer
A. 44% frontExplanation
When the 75kg driver is seated in the race car, the center of gravity (CoG) shifts 144mm forward. This means that more weight is now distributed towards the front of the car. Since the original weight distribution was 64% rear, the remaining 36% was distributed towards the front. When the CoG shifts forward, some of the weight from the rear is transferred to the front. Therefore, the weight distribution with the driver is 36% rear and 64% front. Simplifying this, we get 44% front and 56% rear. Therefore, the correct answer is 44% front.Rate this question:

Two boys each with a stone, move on their Segway respectively in a straight linepath in same direction with a velocity "v". Boy 1 swirls his stone with a string length "r" with angular velocity "w" in a vertical plane in the same sense as that of rotation of wheels of the Segway. As they both cross a milestone, Boy 1's swirling stone detaches and gets a velocity "s=w*R" vertically upwards relative to the Segway. At the same time, Boy 2 also throws his stone in the upward direction with the same magnitude "s ". The two boys continue to move in the same direction.Statement 1: Radial acceleration before detachment of stone is (v^2/r)Statement 2: If the velocity of the Segway v=((w^3)*(r^2)/g), then the Boy 1's stone will land on the same point he crossed the milestone.Statement 3: Both stones will land in their hands respectively
-
Statement 1 and 3 is correct
-
Statement 1 and 2 is correct
-
Only statement 2 is correct
-
Only statement 3 is correct
Correct Answer
A. Statement 1 and 3 is correctExplanation
Statement 1 is correct because the radial acceleration before detachment of the stone can be calculated using the formula a = v^2/r, where v is the velocity and r is the string length.
Statement 3 is correct because both stones will land in their hands respectively. Since Boy 1's stone detaches vertically upwards relative to the Segway, it will eventually come back down and land in Boy 1's hand. Similarly, Boy 2 throws his stone upwards, so it will also come back down and land in his hand.Rate this question:

The head restraint can be __ mm away from the back of the driver's helmet, with the driver in his normal driving position
-
20
-
30
-
50
-
None of these
Correct Answer
A. 20Explanation
The head restraint should be 20 mm away from the back of the driver's helmet when the driver is in their normal driving position. This distance is important to ensure that the head restraint can effectively support the driver's head and neck in the event of a collision or sudden stop, reducing the risk of whiplash or other injuries. A closer distance could potentially cause discomfort or restrict the driver's movement, while a greater distance may not provide adequate support.Rate this question:

-
10mm
-
20mm
-
30mm
-
None of these
Correct Answer
A. 30mmExplanation
The distance between the edge of the vehicle numbers and the edge of the background can be 30mm. This means that there should be a gap of 30mm between the numbers on the vehicle and the background surrounding it. This distance is important to ensure that the numbers are clearly visible and easily readable, without any overlap or confusion with the background.Rate this question:

Why do fuses have lower ratings for DC as compared to AC ?
-
Because of the non-alternating current, DC current exerts one-sided strain on the fuse
-
Because the root mean square of the voltage counts and that is lower for DC
-
Because with AC, arcs in the fuse are extinguished at the first zero-crossing of the AC waveform
-
Because DC voltage is more dangerous and requires more insulation
Correct Answer
A. Because with AC, arcs in the fuse are extinguished at the first zero-crossing of the AC waveformExplanation
Fuses are designed to protect electrical circuits from overcurrent. When a current exceeds the rated value of a fuse, it causes the fuse to heat up and eventually melt, breaking the circuit. In AC circuits, the current alternates direction, which means that when it crosses zero, the arc that forms when the fuse melts is extinguished. This allows the fuse to interrupt the current flow more easily. In DC circuits, however, the current flows in one direction only, causing a one-sided strain on the fuse. As a result, fuses have lower ratings for DC compared to AC.Rate this question:

What will be the minimum value of the resistance between HV ground and LV ground for a maximum tractive system voltage of 315 V?
-
78.75 Ohms
-
78.75 kOhms
-
157.5 Ohms
-
157.5 kOhms
-
250.0 kOhms
Correct Answer
A. 250.0 kOhmsExplanation
The minimum value of the resistance between HV ground and LV ground is 250.0 kOhms. This value is determined by the maximum tractive system voltage of 315 V. The resistance is necessary to ensure proper grounding and to prevent excessive current flow between the high voltage and low voltage grounds. A higher resistance value is required to handle the higher voltage, hence the correct answer is 250.0 kOhms.Rate this question:

If the lap belts and anti-submarine belts are attached to the same point, it must support a load of
-
17.2 kN
-
19.1 kN
-
19.3 kN
-
21.3 kN
Correct Answer
A. 19.1 kNExplanation
If the lap belts and anti-submarine belts are attached to the same point, it means that they are sharing the load. The load that the point must support is the sum of the loads supported by the lap belts and the anti-submarine belts. Since the answer is 19.1 kN, it implies that the lap belts support a load of 19.1 kN and the anti-submarine belts also support a load of 19.1 kN, resulting in a total load of 38.2 kN on the point of attachment.Rate this question:
