The moment created by a force of 12,000 tons and a moment arm of 0.25 foot is __________.
• Moment = Force × Distance is the basic formula to use • Be careful with units: tons for force and feet for distance • Think about whether a zero distance or zero force is involved here
• Which answer choices can you eliminate immediately based on the fact that both the force and the arm are clearly non‑zero? • If you multiply the given force by the given arm, what rough size (order of magnitude) should the moment be compared to 12,000? Much larger, much smaller, or similar? • Check whether 0.25 is less than 1 — how does multiplying by a number less than 1 affect the original value?
• Confirm you are using Moment = Force × Arm (not dividing). • Verify that you keep feet with tons to get ft‑tons as the final unit. • Double‑check your multiplication by 0.25 (¼) before matching to the closest choice.
