### When the vehicles are approved for the dynamic events, which of the following modifications are not permitted to the vehicles

• A.

• B.

Replacement of tires

• C.

• D.

Substitution of suspension parts

B. Replacement of tires
Explanation
When vehicles are approved for dynamic events, they are not allowed to replace their tires. This means that they must use the original tires that came with the vehicle and cannot switch them out for different tires. This is likely because using different tires could potentially give certain vehicles an unfair advantage or disadvantage in terms of performance and handling. All other modifications listed, such as substituting the head restraint, adjusting tire pressure, and substituting suspension parts, may be permitted as long as they meet the event's regulations and safety standards.

### Penalty for submitting SES a week after its due date is

• A.

50 points

• B.

60 points

• C.

70 points

• D.

No penalty

A. 50 points
Explanation
The penalty for submitting SES (presumably referring to a specific assignment or task) a week after its due date is 50 points. This means that if a student fails to submit the SES within the specified deadline, they will have 50 points deducted from their overall score.

### The allowable distance of the drivers helmet from the straight line drawn from the top of the main hoop to the top of the front hoop is

• A.

1.5 inch

• B.

2 inch

• C.

2.5inch

• D.

3 inch

B. 2 inch
C. 2.5inch
D. 3 inch
Explanation
The allowable distance of the driver's helmet from the straight line drawn from the top of the main hoop to the top of the front hoop is between 2 inches, 2.5 inches, and 3 inches. This means that the driver's helmet must not be more than 3 inches away from this straight line, but it must also not be less than 2 inches away. The specific distance within this range will depend on the specific regulations or guidelines in place for the particular situation or event.

Rate this question:

### Prohibited materials for main hoop are

• A.

Aluminium alloys

• B.

Steel

• C.

Composites

• D.

Titanium alloys

A. Aluminium alloys
C. Composites
D. Titanium alloys
Explanation
The main hoop is a structural component in various applications, such as roll cages or safety frames. It is designed to provide protection and stability. The materials listed as prohibited for the main hoop, including aluminium alloys, composites, and titanium alloys, may have certain properties that make them unsuitable for this purpose. For example, aluminium alloys and composites may not possess the necessary strength or rigidity, while titanium alloys may be too expensive or difficult to work with. Therefore, these materials are not recommended for use in constructing the main hoop.

### In the side view of the vehicle, the portion of the Main Roll Hoop that lies below the upper side impact member attachment point should be inclined to the vertical in the forward

• A.

10 deg

• B.

20 deg

• C.

30 deg

• D.

Any angle

D. Any angle
Explanation
In the side view of the vehicle, the portion of the Main Roll Hoop that lies below the upper side impact member attachment point should be inclined to the vertical in the forward direction. This is because an inclined angle helps to distribute the impact forces more evenly and redirect them away from the occupants in the event of a side collision. By inclining the Main Roll Hoop at any angle, it provides better structural integrity and enhances the safety of the vehicle.

### The distance between front hoop and steering wheel can be

• A.

225mm

• B.

250mm

• C.

275mm

• D.

300mm

A. 225mm
B. 250mm
Explanation
The correct answer for the distance between the front hoop and the steering wheel can be either 225mm or 250mm. This indicates that there might be some variability or options available in terms of adjusting the distance between these two components. The specific distance chosen may depend on factors such as personal preference, comfort, or specific requirements of the vehicle or driver.

• B.

6.2 inches

• C.

150mm

• D.

170mm

A. 160mm
B. 6.2 inches
C. 150mm
Explanation
The correct answer is 160mm. This means that the Main Hoop braces can be attached at a distance of 160mm to the top of the Main Hoop. The other options, such as 6.2 inches, 150mm, and 170mm, are incorrect.

### Length of impact attenuator should not exceed

• A.

200mm

• B.

100mm

• C.

7.8 inches

• D.

No such rule

D. No such rule
Explanation
There is no specific rule or requirement regarding the maximum length of an impact attenuator. The length of an impact attenuator can vary depending on the specific application and the design requirements. Therefore, none of the given options accurately state the maximum length of an impact attenuator.

### No part of the anti-intrusion plate should permanently deflect more than

• A.

1 inch

• B.

2 inch

• C.

50.8mm

• D.

25.4mm

A. 1 inch
D. 25.4mm
Explanation
The correct answer is 1 inch or 25.4mm. This means that no part of the anti-intrusion plate should permanently bend or deform more than 1 inch or 25.4mm. This is important for maintaining the structural integrity and effectiveness of the plate in preventing intrusions or break-ins. Any greater deflection could compromise its ability to provide security and protection.

• B.

8mm

• C.

5.5mm

• D.

0.25 inch

A. 7mm
C. 5.5mm
D. 0.25 inch
Explanation
The correct answer includes three options: 7mm, 5.5mm, and 0.25 inch. This suggests that the thickness of the steering template can be measured in different units of measurement, including millimeters and inches. The options provide a range of thicknesses for the template, allowing for flexibility in the design and use of the steering template.

### Distance between shoulder harness mounting points can be

• A.

200mm

• B.

6 inch

• C.

160mm

• D.

8 inch

A. 200mm
D. 8 inch
Explanation
The correct answer is 200mm and 8 inches. These measurements refer to the distance between the shoulder harness mounting points. The first measurement, 200mm, is in metric units, while the second measurement, 8 inches, is in imperial units. Both measurements represent the same distance, just expressed in different unit systems.

### Ground clearance should be

• A.

Minimum 2 inches

• B.

Minimum 3 inches

• C.

Minimum 50.8mm

• D.

Sufficient enough

D. Sufficient enough
Explanation
The correct answer is "sufficient enough". This implies that the ground clearance should be enough to meet the requirements or standards necessary for the specific situation or purpose. It suggests that there is no specific numerical value or measurement given for the ground clearance, but it should be adequate for the intended use.

### Minimum tread depth should be

• A.

3/32 inches

• B.

2.3mm

• C.

2.4mm

• D.

3.3mm

A. 3/32 inches
C. 2.4mm
Explanation
The correct answer is 3/32 inches or 2.4mm. This is the minimum tread depth that should be maintained for safe driving. Adequate tread depth is crucial for proper traction and performance of the tires, especially in wet or slippery conditions. Tires with insufficient tread depth can lead to reduced grip, longer stopping distances, and an increased risk of hydroplaning. Therefore, it is important to regularly check and maintain the tread depth of your tires to ensure safe driving.

### Minimum allowable steering system free play is

• A.

7 deg

• B.

6 deg

• C.

5.5 deg

• D.

No such rule

D. No such rule
Explanation
There is no specific rule or regulation that states a minimum allowable steering system free play. The amount of free play in the steering system can vary depending on the design and condition of the vehicle. It is generally recommended to have as little free play as possible to ensure precise steering control, but there is no specific numerical value mandated by any rule or regulation.
