In a flight control system, the control cable is allowed an elongation of 3% due to wear. The length from the manufacturer is 78cm, what is its maximum used length?
- 2.34 cm
- 78.34 cm
- 80.34 cm
Explanation from PART66Online
A 3% elongation adds 3% of the original length on top of it. Three percent of 78 cm is 2.34 cm, so the maximum used length is 78 + 2.34 = 80.34 cm. The 2.34 cm answer gives only the increase, not the total length.

Why isn't 80.34cm? I didn't understand it.

78+(78*3/100) = 80.34 or
78+(78*0.03) = 80.34 or
78 * 103/100 = 80.34 or
78 * 1.03 =80.34
78+(78*0.03) = 80.34 or
78 * 103/100 = 80.34 or
78 * 1.03 =80.34

elongation is the process of lengthening something, thus the length of the cable is increased by 3%. therefore 3% of 78 is 2.34.
The new length is 78+2.34 = 80.34cm
The new length is 78+2.34 = 80.34cm
