Explanation

It is not permissible to fabricate the Front Hoop from more than one piece of tubing.

Submit
12. Minimum width of scatter shield must be:

Explanation

The minimum width of the scatter shield must be three times the width of the chain. This is because the scatter shield is designed to provide protection and prevent any debris or particles from scattering outwards. By having a width that is three times the width of the chain, it ensures that there is enough coverage to effectively contain any potential scattering.

Submit
13.  In a four speed four-stroke Diesel engine, the intake valve

Explanation

The correct answer is "opens at 20° before T.D.C. and closes at 35° after B.D.C." In a four-stroke Diesel engine, the intake valve opens before the piston reaches top dead center (T.D.C.) to allow air or fuel-air mixture to enter the combustion chamber. It closes after the piston reaches bottom dead center (B.D.C.) to seal the combustion chamber and allow compression to occur. This timing ensures efficient intake and compression strokes for proper engine operation.

Submit
14. The gap between restraint and the back of the driver’s helmet must be 

Explanation

The gap between restraint and the back of the driver's helmet must be 25 mm. This is important for ensuring the safety of the driver by providing adequate space between the restraint and the helmet. A larger gap could result in the helmet being pushed forward during an impact, potentially causing injury to the driver's head and neck. Conversely, a smaller gap may not provide enough space for the helmet to move freely and absorb the impact effectively. Therefore, a 25 mm gap is the optimal requirement for maintaining driver safety.
