In order to obtain a quick relaase from the magnets, it is necessary
to use the minimum current that will do the job. It is evident
that a frictional force which may be as great as 50 percent of the
weight needs to be reduced. Also, the shock absorbers are supposed
to furnish the necessary air cushioning over the last inch of travel
consequently air cushioning in the sheaths is undesirable.
