In general, the discriminant is an algebraic expression that gives. information about the roots of a polynomial. In the case of a quadratic equation the discriminant is the part of. the quadratic equation that is under the radical sign.
How to Select Dampers and Louvers. Dampers and louvers are used to control the flow of air in a process system or enclosed area. Dampers are usually motorized or manually-adjustable for flow control. Louvers are often fixed for a constant flow rate.
But wait that's not all. If you look closely at the below picture you'll find a black part too that runs inside the spring. This is a shock absorber/damper which is also a part of vehicle suspension setup. In short : The coil springs help in energy absorption whilst the dampers help in energy dissipation. Had there been no dampers and only springs the vehicle would have continued to oscillate back and forth until the vibrations died out of natural damping.
