70% to passWhich figure shown in the illustration, is the nut lock improperly used? Illustration GS-0156

A"A"
B"B"
C"C" and "D"
D"C" and "E"
AI Explanation
The correct answer is D) "C" and "E". The nut lock is being improperly used in figures "C" and "E" of the illustration GS-0156. The nut lock is designed to prevent the nut from loosening, but it must be properly installed with the split end of the lock oriented in the direction of the nut's tightening rotation. In figures "C" and "E", the nut lock is installed incorrectly, with the split end oriented in the opposite direction, which would not effectively prevent the nut from loosening. The other answer choices are incorrect because "A" shows the nut lock properly installed, and "B" does not depict a nut lock at all.
