Question 1859Deck General70% to pass
Using a safety factor of five, determine the safe working load of a line with a breaking strain of 20,000 pounds.
AI Explanation
The correct answer is A) 4,000 pounds.
To determine the safe working load of a line, the breaking strain is divided by a safety factor. The safety factor accounts for unknown variables, such as wear and tear, improper usage, and other factors that could compromise the line's strength. Using a safety factor of 5, the safe working load is calculated by dividing the breaking strain (20,000 pounds) by the safety factor (5), which results in a safe working load of 4,000 pounds.
The other options are incorrect because:
B) 5,000 pounds is too high for a safety factor of 5.
C) 20,000 pounds is the breaking strain, not the safe working load.
D) 100,000 pounds is significantly higher than the correct answer.
