1. The upper and lower members of the front bulkhead is 180mm and 150mm respectively and use a standard I.A.

Insufficient information

We will need a diagonal brace of tube of dimension 1.00"X0.049"

We will need a X brace of tube of dimension 1.00"X0.049"

Options 1 & 2

Explanation

not-available-via-ai

2. What is the minimum thread depth of a wet tyre ?

None of these

2.3 mm

2.1 mm

3/34"

3. A car is going around a corner of constant radius of 34m. What speed does it need go around to show sufficient roll-over stability ?

80.567 km/hr

86.5 km/hr

79.45 km/hr

83.567 km/hr

To ensure sufficient roll-over stability while going around a corner, the car needs to maintain a higher speed. The correct answer of 86.5 km/hr suggests that this is the speed at which the car can maintain stability without rolling over. Going at a lower speed may cause the car to lose stability, while going at a higher speed may result in loss of control. Therefore, 86.5 km/hr is the appropriate speed for the car to go around the corner with sufficient roll-over stability.

Explanation

To ensure sufficient roll-over stability while going around a corner, the car needs to maintain a higher speed. The correct answer of 86.5 km/hr suggests that this is the speed at which the car can maintain stability without rolling over. Going at a lower speed may cause the car to lose stability, while going at a higher speed may result in loss of control. Therefore, 86.5 km/hr is the appropriate speed for the car to go around the corner with sufficient roll-over stability.

4. Of what thickness should a shield be made for the fore-mentioned high pressure lines ?

0.1 mm steel

0.4mm aluminium

0.3 mm steel

Not required

A shield should be made of 0.1 mm steel for the fore-mentioned high pressure lines. This thickness is likely sufficient to provide adequate protection against any potential hazards or damage caused by the high pressure. Steel is a strong and durable material that can withstand high pressure, making it a suitable choice for shielding purposes.

5. Tick the correct options with respect to jacking points.

The jacking point is 210mm above the ground when the wheels are 15mm above the ground

The jacking point is 60 mm above the ground when the car has 15 mm of jounce

The length of the jacking bar is 280 mm

I.d. is 26 mm

not-available-via-ai

Explanation

not-available-via-ai

6. Which the following would not pass the technical inspection?

The distance between shoulder harness points is 220 mm

The shoulder harness attachment point is sheared in at 61.23 sq.in

The thickness of a Y-type shoulder strap is 3"

The harness is mounted on a bent tube and can bear 7kN per attachment

The thickness of a Y-type shoulder strap being 3" would not pass the technical inspection because it exceeds the maximum allowable thickness for a shoulder strap.

Explanation

The thickness of a Y-type shoulder strap being 3" would not pass the technical inspection because it exceeds the maximum allowable thickness for a shoulder strap.

7. At what pressure is a hydraulic line considered a high pressure line ?

300 psi

250 psi

350 psi

320 psi

A hydraulic line is considered a high pressure line when the pressure reaches or exceeds 300 psi. This means that once the pressure in the hydraulic line reaches 300 psi or higher, it is classified as a high pressure line.

Explanation

A hydraulic line is considered a high pressure line when the pressure reaches or exceeds 300 psi. This means that once the pressure in the hydraulic line reaches 300 psi or higher, it is classified as a high pressure line.

8. The test rpm for a engine with stroke length 300mm

1900 rpm

2000 rpm

4500 rpm

1500 rpm

The correct answer is 1500 rpm. The RPM (revolutions per minute) of an engine is a measure of how many complete rotations it makes in one minute. A longer stroke length means that the piston travels a greater distance within the cylinder, resulting in a slower rotation speed for the same RPM. Therefore, an engine with a stroke length of 300mm would have a lower RPM compared to engines with shorter stroke lengths.

The correct answer is 1500 rpm. The RPM (revolutions per minute) of an engine is a measure of how many complete rotations it makes in one minute. A longer stroke length means that the piston travels a greater distance within the cylinder, resulting in a slower rotation speed for the same RPM. Therefore, an engine with a stroke length of 300mm would have a lower RPM compared to engines with shorter stroke lengths.

9. With regarding the the front bulkhead the following would pass the inspection.

The upper support member is attached at 2" below the top of the front bulkhead

The upper support member is 5" above upper side impact member attachment point

Its made of steel tubing of 1"X0.095"

Diagonal brace is of 1"X0.065"

The upper support member being attached 2" below the top of the front bulkhead ensures that it provides adequate structural support to the front of the vehicle. This positioning allows the support member to effectively distribute any impact forces and prevent any damage to the front bulkhead. By attaching the upper support member at this specific distance, it ensures that it is properly aligned with the rest of the front structure and can effectively withstand any potential collisions or impacts.

10. Tick the correct statements

Scatter shields for belt are made of 2.65 mm thick steel

For a plastic belt drive aluminium shield of 2 mm thickness is used

For a plastic belt drive the thickness is 1.7 times the width of the belt

Fasteners are of 8 mm metric grade 8.8

The answer is correct because it aligns with the information provided in the statements. The first statement states that scatter shields for the belt are made of 2.65 mm thick steel. The third statement confirms that for a plastic belt drive, the thickness is 1.7 times the width of the belt. Therefore, the answer accurately reflects the given information.
