Describe the action & operation of reative and non-reative suspension system?
this topic has to do with automotive engineering and specifically on suspension system of automotive vehicle.

A reactive suspension responds to driveline torque. A non-reactive system does not.So, for instance, a simple leaf spring is reactive (not good). This is because the suspension system (the leaf) serves the dual purpose of countering driveline torque. Assume rear-wheel drive and the car is accelerating. The axle reacts to the force of the wheel against the pavement by trying to twist in the opposite direction (the differential tries to torque "up"). In reaction to this, the front part of the leaf is compressed more while the back is stretched a bit. The leaf assumes an "S" shape. The suspension now behaves differently. A simple band-aide is traction bars (see second web site for an example).
In response to this problem some fairly complex suspensions such as "trailing arm" "semi-trailing arm", torsion beam, multi-link and Weissach axle suspension were developed. See final link.
From the link below:
[t]he term "non-reactive" means that the suspensiondoes not react appreciably to torque forces applied toa drive axle, primarily during acceleration. Being non-reactive substantially eliminates driveline torque induced problems.
