Accepted Answer

Visual warning and an aural alert.

Answer

Bell.

Answer

Aural alert only.

Answer

Visual warning only.

Question 4

The octane rating of a fuel and compression ratio of a piston engine have which of the following relations?

Accepted Answer

The higher the octane rating is, the higher the possible compression ratio is

Answer

The lower the octane rating is, the higher the possible compression ratio is

Answer

The higher the octane rating is, the lower the possible compression ratio is.

Answer

Compression ratio is independent of the octane rating.
