Which of the following statements about the Front Bulkhead support is true?

The upper support member must be attached to the front bulkhead a maximum of 50 mm below the top-most surface of the front bulkhead, and attached to the front hoop a maximum of 50 mm below the upper side impact member. If the attachment point of the upper member ist greater than 100 mm above the upper side impact member , node-to-node triangulated bracing is required to transfer load to the side impact member.

The upper support member must be attached to the front bulkhead a maximum of 50 mm below the top-most surface of the front bulkhead, and attached to the front hoop a maximum of 50 mm below the upper side impact member. If the attachment point of the upper member is lower than 100 mm above the upper side impact member, node-to-node triangulated bracing is required to transfer load to the main hoop

The upper support member must be attached to the base of the front bulkhead and the base of the front hoop.

The upper support member must be attached to the front bulkhead a maximum of 50 mm below the top-most surface of the front bulkhead, and attached to the front hoop a maximum of 50 mm below the left side impact member. If the attachment point of the upper member is greater than 100 mm above the upper side impact member, node-to-node triangulated bracing is required to transfer load to the main hoop.

The lower support member must be attached to the base of the front bulkhead and the base of the side impact member.

The perimeter shear strength of the monocoque laminate in the front bulkhead support structure must be at least 4 kN

Which of the following illustrations from the rulebook is wrong?

On fluid mechanics, boundary is defined as the layer of fluid in the immediate vicinity of a bounding surface where the effects of viscosity are significant. On a boundary layer:

The flow is laminar

The Bernoulli equations do not apply

The flow is turbulent

The laws of momentum, energy and mass conservation do not apply

None

The Bernoulli equations apply

Regarding the Fire Extinguishers, it is correct to say that:

One extinguisher mus accompany the vehicle wherever the vehicle is moved, and the second must readily be available in the team's paddock area

Each team must have at least two dry chemical/ dry powder fire extinguishers with a minimum firefighting agent capacity of 0.8 kg

Only extinguishers with the rating 10 BC, 1A 10BC must be equipped with a manufacturer installed pressure charge gauge

The team must present three unused and in date fire extinguishers at the pre inspection
