Which statement is true about selecting elevator sizes?

• A. Start small and increase size as leverage decreases
• B. Start large and decrease size as leverage increases
• C. Use the largest elevator every time
• D. Size is irrelevant to leverage

Answer: (A)

When choosing an elevator or lifting device, think about how much help you get from the mechanism itself. The bigger the device, the more leverage (mechanical advantage) it provides, which means you need less input force to lift the same load. Because you want to control the lift safely and comfortably, you start with the smallest device that can potentially do the job. If you find that you’re unable to lift or control the load effectively—because the required force is too high or the movement is too slow—you switch to a larger device to gain more leverage. This approach keeps effort manageable while still meeting the lift needs.

Starting with a large device every time wastes effort and can create unnecessary handling challenges, and saying size doesn’t matter for leverage isn’t accurate because the whole point of the device is to change the force you must apply.
