Question 1 of 2066636ee728f7522a1c517860

The deck load capacity of a compartment into which you intend to load a cargo of soft brick is 380 lbs. per sq. ft. The stowage factor of the brick is 21.3. Disregarding broken stowage, what is the maximum height the brick may be stacked without endangering the structure?

🔍 Key Concepts

• Stowage factor and what its units mean in practical terms (cubic feet per long ton) • How to convert a stowage factor into weight per cubic foot of cargo • Relating deck load limit (lbs/sq ft) to the height of cargo stacked (ft)

💭 Think About

• First, express the brick’s stowage factor as a weight per cubic foot so you know how many pounds each vertical foot of brick will put on one square foot of deck. • Then compare that weight per vertical foot with the deck load capacity (380 lbs/sq ft) to find how many feet of height will reach the deck limit. • Check which choice best matches the height you get when you divide the allowable load (lbs/sq ft) by the cargo’s weight per cubic foot (lbs/cu ft).

✅ Before You Answer

• Verify that you are using long tons (2240 lbs), not short tons, when working with stowage factors in ft³/ton. • Be sure you convert 21.3 ft³ per ton into lbs per ft³ before using the deck load limit. • Confirm that your final step is deck load limit (lbs/sq ft) ÷ cargo density (lbs/cu ft) to get a height in feet.
