Q

A thirty-pound plate would be which thickness?

🔍 Key Concepts

• Relationship between plate thickness and weight per square foot for steel plate • How a change in thickness (e.g., from 3/8" to 3/4") affects total weight if the area stays the same • Using relative comparisons instead of exact formulas when you don’t know weight-per-foot tables by memory

💭 Think About

• If a certain area of plate weighs 30 pounds, what happens to that weight if you double the thickness of the plate but keep the same area? • Compare each option: which thickness would reasonably give around 30 pounds, assuming a typical small plate size used in exam examples? • Think about which thicknesses are lightest and heaviest and eliminate any that would be clearly too light or too heavy for 30 pounds.

✅ Before You Answer

• Be clear that all options refer to thickness of the same material and area, so only thickness changes the weight • Remember that weight is directly proportional to thickness for the same material and area • Eliminate any thickness that would obviously be too thin or too thick to match a 30‑pound plate under typical exam assumptions
