Q

The time required to incline from bow down to stern down and return to bow down again is called __________.

🔍 Key Concepts

• Ship motions in waves: pitch vs. roll vs. heave • Definition of a period of motion (time for one full cycle) • Relationship between bow up/bow down and fore‑and‑aft motion

💭 Think About

• Which motion involves the ship rotating about a transverse (athwartship) axis, causing the bow and stern to move up and down? • In the description, when have you completed one full cycle of this motion—at the first stern down, or when you return to bow down? • Which of the choices are actually forces or moments, and which are time intervals describing motion?

✅ Before You Answer

• Identify which options refer to time for a complete cycle of motion, not a force or moment. • Confirm which ship motion term is associated with fore‑and‑aft tilting (bow and stern), not side‑to‑side. • Eliminate any term you know is used for lateral stability tests or sideways motion, since the question clearly describes fore‑and‑aft movement.
