Assembly
➀
Remove the three legs from the clips on the bottom
of the plastic force table disk.
➁
Screw the legs into the holes on the bottom of the
disk (see Figure 1.)
➂
Attach three pulleys and clamps to the rim of the
disk. If more than two forces are to be added, use
the desired number plus one pulley and clamp for
the equilibrant force.
There are two ways to attach the strings to the table:
The first way uses the conventional ring in the center
of the table and the second way uses an anchor string
through the hole in the center of the table. The advan-
tage of the anchor string is that a higher precision can
be achieved because a single knot is being centered
instead of the massive ring. The anchor string keeps
the masses from falling to one side when the system is
not in equilibrium.
➤
NOTE: In both methods it is important to
adjust the pulleys so that the strings are parallel
to the top surface of the Force Table, and as
close to the top surface as possible. When
adjusting the pulleys, don't let the ring rest on the
top surface.
