This study guide covers free-body diagrams (FBDs) in fluid mechanics, focusing on key forces like weight, buoyant force, normal force, and resistive force. It provides a step-by-step guide for drawing effective FBDs and presents examples of FBDs for objects floating, sinking, and resting at the bottom of a fluid. The guide also emphasizes common mistakes to avoid, offers a memory aid, and includes practice questions with an answer key. Finally, it highlights key concepts for exam preparation, including buoyancy and applying Newton's Laws.
