The magneto-rheological fluid used in some shock absorbers and struts contains:
A) Small, suspended metal particles
B) A dye for leak detection purposes
C) A viscous coupling additive
D) Pour point depressors

Question

Quizplus · Accepted Answer

The magneto-rheological fluid contains small, suspended metal particles, which are attracted to or repelled by magnetic fields to adjust the stiffness of the shock absorber or strut. This allows for adaptive damping and improved handling in various driving conditions.
