5.2 Set-up for coupled pendulum with sen-

sors

Set up the pendulum stand as described in
4.3.

Attach a force sensor to the cross bar with
the knurled screw.

Stretch a coupling spring between the pen-
dulum rod and the force sensor.

Clamp the bearing rod into the double clamp
in such a way that the coupling springs and
pendulum rod move in roughly the same
plane as the hook of the force sensor.

Set up the second force sensor in the same
way.

Couple the two pendulum rods together with
the tension spring.

Connect the force sensors to the inputs for
channels A and B of the MEC amplifier
board.

Connect the outputs to an oscilloscope and
start the experiment.
