Using the following information, determine if there could be a vibration problem in each of the three vehicles based on the measurements taken by an inclinometer of their driveline angles. A difference greater than 0.5 degrees is too large and will cause vibration.

Vehicle	Front Working Angle	Rear Working Angle	Difference between Front and Rear Angle	Could there be a vibration problem?
1	16.5 degrees	16 degrees
2	10 degrees	13 degrees
3	15.5 degrees	14.5 degrees

 

Solution:

Vehicle	Front Working Angle	Rear Working Angle	Difference between Front and Rear Angle	Could there be a vibration problem?
1	16.5 degrees	16 degrees	16.5 - 16 0.5 degrees	No
2	10 degrees	13 degrees	13 - 10 3 degrees	Yes
3	15.5 degrees	14.5 degrees	15.5 - 14.5 1 degree	Yes
