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 
4 Stand rod with external thread 
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 
Fig 1 Set-up for coil spring pendulum without sensors 
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.
