What percentage of the load does the pulling force represent in the steel block on wheels scenario (10500 LBS load, 525 LBS force)?

• A. 1%
• B. 5%
• C. 10%
• D. 0.5%

Answer: (B)

The key idea is turning the pulling force into a share of the total load by using a simple ratio. Divide the pulling force by the load and convert to a percentage: 525 ÷ 10,500 = 0.05, which is 5%. So the pulling force represents 5% of the total load.

For context, this kind of ratio helps assess how large a fraction of the weight you’re moving or overcoming with your pulling effort, which in turn informs equipment sizing and safety margins. The other options would correspond to 1% (105 lbs), 10% (1,050 lbs), or 0.5% (52.5 lbs), which don’t match the given numbers.
