1 Double clamp

2 SW cross bar

3 Base plate

1. Description

Stand equipment for simple, easily understood
and stable experiment set-ups, e.g. for investi­gating mechanical oscillations and waves using
sensors from the SW sensors sets, 230 V, 50/60
Hz (1012850) or 115 V, 50/60 Hz (1012851).

Includes the SW base plate as a secure base
that will not tip, with three specially threaded
sockets for attaching stand rods with external
and internal threads in such a way that they
cannot lean over and with the capability of being

5 Stand rod with internal and external thread

extended using a second rod with external
thread. Two double clamps are provided for
attaching the SW cross bar or additional stand
rods of 10 mm diameter.

The SW cross bar acts as a multi-functional
mounting piece to be placed between rods
screwed into the base plate and designed for
setting up a Wilberforce pendulum, a physical
pendulum or a string pendulum in conjunction
with the dynamic force sensors from the SW
sensors set.

4. Operation

4.1 Set-up without sensors

The following additional equipment is necessary
in order to set up a coil spring pendulum:

1 Stand rod, 280 mm, 10 mm diam. 1012848
1 Coil spring, 1 weight

• Screw the stand rods with both external and

4.2 Set-up for mechanical pendulums with
sensors

The following additional equipment is necessary
in order to carry out the experiments:

1 SW stand equipment set 1012849
1 SW sensors set (@230V) 1012850

or
1 SW sensors set (@115V) 1012851

1 USB oscilloscope 2x 50 MHz 1017264
1 PC, operating system Win XP, Vista, Win 7

1 SW Wilberforce pendulum set 1012844
or
1 SW string pendulum set 1012854
or
1 SW physical pendulum set 1012853

Notes on assembly:
See instruction manuals for the pendulums
listed.

internal threads into the outer threaded so­ckets of the base plate.

• Extend both rods by screwing rods with ex-

ternal thread only onto the ends of them.

• Attach double clamps near the top of both

stand rods and turn them to point inwards.

• Set up stand rod, 280 mm, 10 mm diam.

• Suspend a coil spring and weight from the top.

• Packaging and compo-

nents should be dis­posed of, where neces­sary, at local recycling
centres.
