Automotive Information

Which of the following statements about an inline cylinder configuration is false?

works well in eight cylinder engines

An inline cylinder configuration places the cylinders in a single row either completely vertical or slanted. Due to this arrangement, an inline cylinder configuration makes the engine longer and, although it works well in four cylinder engines, performace suffers in larger engines due to the difficulty in evenly distributing the air-fuel mixture over the length of the engine.

Mechanical Comprehension

Normal force is generally equal to the __________ of an object.

weight

Normal force arises on a flat horizontal surface in response to an object's weight pressing it down. Consequently, normal force is generally equal to the object's weight.

Mechanical Comprehension

Gear ratio indicates which of the following about two connected gears?

mechanical advantage

The mechanical advantage (amount of change in speed or torque) of connected gears is proportional to the number of teeth each gear has. Called gear ratio, it's the ratio of the number of teeth on the larger gear to the number of teeth on the smaller gear.  For example, a gear with 12 teeth connected to a gear with 9 teeth would have a gear ratio of 4:3.

General Science

Which of the following is not a characteristic of the Sun?

formed 2.6 billion years ago

The Sun is a G-type main-sequence star (G2V) but is informally known as a yellow dwarf star. Composed of 73% hydrogen and 25% helium, the hot plasma that makes up the Sun reaches 9,900°F (5,505°C) at the surface. It formed approximately 4.6 billion years ago and makes up 99.86% of the mass in the solar system.

Automotive Information

The fluid reservoir stores the __________ that the master cylinder uses to maintain hydraulic pressure.

brake fluid

The fluid reservoir stores the brake fluid that the master cylinder uses to maintain hydraulic pressure.

Automotive Information

How are the cylinders numbered in V-type engines?

cylinder numbering varies by manufacturer

In V-type engines the numbering sequence varies by manufacturer.

General Science

Bronchioles, alveolus, and capillaries are vital parts of which bodily system?

respiration

The trachea branches into the left and right bronchi which each lead to a lung where the bronchi subdivide into smaller tubes called bronchioles. Each bronchiole ends in a small sac called an alveolus which allows oxygen from the air to enter the bloodstream via tiny blood vessels called capillaries.
