{ "item_title" : "Ship Stability for Deck Officers", "item_author" : [" Talor Press "], "item_description" : "Ship stability is the part of deck work where a small error in a weight or a sounding becomes a large error in GM, list or trim. This workbook teaches the subject in thirty short lessons and tests every step with practice. The lessons run from the basics (G, B, M, KM, KG, GM and the righting lever GZ) through weight changes, shifts of weight, free surface effect, list and angle of loll, draught, trim, TPC and MCTC, docking and grounding, the GZ curve, Simpson's rule, KN cross curves, dynamical stability, and weather, grain, icing and rolling. The last part covers flooding, damage stability and the action of the watchkeeper. Each lesson ends with an eight-question knowledge check. A 40-question final review brings the total to 280 practice questions, and the answer key gives the reason for each answer. Inside you will find: - 30 lessons in six parts, each part closed by a review- 280 practice questions with an answer key- 9 labelled figures drawn for learning- Step-by-step calculation methods and quick reference tables- 8 worked loading scenarios with the arithmetic shown- 42 practice calculations and 23 practice situations- 10 case studies and 20 oral examination questions with model answers- 18 blank forms for loading conditions, tank soundings, draughts and heavy lifts- A revision checklist and a glossary of 61 terms Written for deck cadets, watchkeeping officers and anyone preparing for stability examinations. All figures in the book are examples for learning. This is an educational guide and not a substitute for a ship's approved stability information, loading instrument or company procedures, which must always govern real decisions.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/9/79/819/050/9798190501438_b.jpg", "price_data" : { "retail_price" : "10.99", "online_price" : "10.99", "our_price" : "10.99", "club_price" : "10.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
