What is the amount of tension that should be applied to the spring balance of the end of a steel tape to yield the proper tension to the 75-ft increment? (Assume the final measurement in the line of tape is 75 ft and the normal 100-foot tape tension is 10 pounds (lbs).)
A)7)5 lbs
B)10 lbs
C)75 lbs
D)None of the above

Quizplus · Accepted Answer

7.5 lbs. of tension should be applied to the 75-ft increment of tape.
Solution: Use the steel tape correction factor applied to the length of measurement
Tension = 10 lbs. /100 ft = 0.1 lb. /ft
Correction = (0.1 lb. /ft) (75 ft) = 7.5 lbs
