describe the action & operation of reative and non-reative suspension system?

A reactive suspension responds to driveline torque.  A non-reactive system does not.  \n\nSo, 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).\n\nIn 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.\n\nFrom the link below:\n[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.

a suspension is a liquid and a solid in which the solid is in suspension in the liquid.  a good example is something like dirt and water.  the dirt is a solid and it is suspended in the water.  a colloid is a misture of two liquids.  an example is water and alcohol.  the alcohol is slightly soluble in water and so they make a colloid.

It is a dc motor working in conjunction with an inductor and a quartz crystal.\n\nThe quartz crystal delivers regulated pulses to the inductor which sends a varying magnetic field to a magnet which spins, the motor only needs two poles as the magnetic field changes continuously.

Active transport involves the movement of substances across a cellular membrane from an area of low concentration to an area of high concentration WITH the expenditure of cellular energy. Passive tranport is the movement of substances from a high concentration area to a low concentration area WITHOUT the expenditure of cellulary energy. \n\nOsmosis is the flow of water through a semi-permeable membrane from a high solute concentrated area to a low solute concentrated area. Osmosis is an example of passive transport, as the flow of water follows the concentration gradient.

The control system is designed to detect all requests, decide whether to go up or down (depending on whether the car is empty or has passengers already heading up or down) and whether to pass or stop each floor.  The elevator may be part of a bank of two or more elevators requiring logic to handle the most people efficiently without ignoring anyone who has pressed the button.

It is usually self-hoisting. There is motor and gear assenbly that lifts the crane within the tube (usually a future elevator shaft) the is constructed around it. Then it is bolted down and goes back to work.

there is an engine i saw that has no moving parts. just magnets that attract water in one end and out the other, but it only works in salt water.

An Hydraulic lift, is a lift that works by using hydraulic oil to raise and lower it,an hydraulic ram is fitted to the under side of the lift. Other lifts work by means of the traction sheave driving the lift car up and down. An Hydraulic lift is not as fast as normal lift, but can take greater weight, and the other thing about an Hydraulic lift is that the lift motor room can be remote from the lift shaft unlike a normal lift.

Magneto-rheological fluids can change their viscosity in response to an applied magnetic field. Automobile suspension dampers (which are misleadingly called shock absorbers) that use these fluids can provide variable damping to match the characteristics of the road. They are also proposed for use in adaptively damping buildings against seismic vibrations, since they can be controlled to provide optimum damping of the particular frequency content of the disturbance (ref.).

An object in motion will remain in motion until acted upon by an external force. An object at rest will remain at rest until acted upon by an external force.

Hey! I just finished learning about active transport! The teacher confused me soooo bad! I had to have a friend in my class explain it to me. I would suggest going to google and typing in "active transport" and clicking on the news tab on the top. good luck with your project!
