Question 1 of 27070

If a ship is supported on the crest of a wave amidships, the vessel is subjected to __________.

🔍 Key Concepts

• longitudinal stresses on a ship (bending along her length) • difference between hogging and sagging (which part is higher: bow/stern or midship?) • how a ship sits on a wave crest vs. wave trough

💭 Think About

• Visualize the ship from the side: if the middle is on top of a wave crest and the bow and stern are more in the troughs, which part is more supported and tends to rise? • In that situation, does the hull bend with the middle higher than the ends or the ends higher than the middle? Match that picture to the correct stress term. • Eliminate the options that describe motions (rotations) rather than bending stresses along the ship’s length.

✅ Before You Answer

• Identify which answer choices are about bending stress (shape of the hull) versus which are about ship motion (pitch/yaw). • Recall: hogging vs sagging is about whether the midship or the ends are higher relative to each other. • Make sure your choice matches a condition where the wave crest is under midships and the ends are less supported.
