🔍 Key Concepts

• Tons Per Inch Immersion (TPI) – what it represents and how it links added weight to change in draft • Relationship: Change in draft (inches) = Weight loaded (tons) ÷ TPI • Converting a decimal number of inches into feet and inches and then comparing with multiple‑choice options

💭 Think About

• First, calculate how many inches of immersion correspond to loading 1200 tons using the given TPI. What is the exact formula, and what units must you use? • Take your calculated change in draft (in inches) and add it to the original mean draft of 32'-05". How do you correctly combine feet and inches here? • Once you have the new draft as feet and inches (it may not come out to a whole inch), which answer choice is numerically closest to your computed value?

✅ Before You Answer

• Be sure you actually divide weight (1200 tons) by TPI (178 tons per inch) to get change in draft in inches. • Check that you do not convert the original draft into decimal feet and then forget to convert back when comparing with the answer choices. • After adding the inches, verify whether you cross 12 inches, and if so, convert that excess into an extra foot before matching the choices.
