Components Package (ME-9505)
Mounted Scale Assembly
The mounted scale has four strong magnets in its base. The tube is marked in
newtons (N), ounces (oz.) and millimeters (mm). The thumbnut allows the top
hook to be raised or lowered in order to align the red indicator disk with the
zero mark on the tube.
To zero the scale, mount the scale on the statics board. Leave the bottom hook
empty. Unscrew the thumbnut a few turns. Rotate the top hook clockwise
(left-to-right) to lower the indicator disk and counter-clockwise (right-to-left)
to raise the indicator disk. When the disk is aligned with the zero mark on the
tube label, tighten the thumbnut to hold the top hook in place.
To move the scale on the statics board, hold the scale by the tabs on the base
and push or pull the scale to the desired location. To remove the scale from the
statics board, lift one or both of the tabs on either side of the base away from
the board.
Large and Small Pulleys and Double Pulley Block
The Statics System comes with two Small Pulleys and one Large Pulley
mounted on magnetic bases. It also includes a Double Pulley Block (that does
not have a magnetic base). The Double Pulley Block is designed for
block-and-tackle experiments. A support thread can be tied to either end of the
Double Pulley Block.
All the pulleys have low friction ball bearings. The smaller pulleys are 2.41
cm (0.850”) outside diameter (OD) and 1.65 cm (0.650”) inside diameter (ID).
The larger pulleys are 2.79 cm (1.10”) OD and 2.28 cm (0.90”) ID.
Please use the tabs on the base of the components when moving them around or removing them from the statics
board.
Mass Cart and Friction Block
The Mass Cart and Friction Block are
designed to be used with the Inclined Plane
Assembly. The Mass Cart has low friction ball
bearings in each wheel and a metal rod in the
center for stacking extra masses. A thread can
be attached at either end.
The Friction Block is made of beech wood. It
has an “eye” hook at one end and is covered
with felt on the bottom and one side. Its dimensions are 2.54 cm by 5.08 cm by 6.35 cm (1.0” by 2.0” by 2.5”).
