Resonance Structures: Beam and Tower

The PASCO Structures System can be used to demonstrate resonance in complex structures. Resonance is the

tendency of a structure to oscillate at a greater amplitude at some frequencies than at others. These are known as

the structure’s resonance frequencies. At these frequencies, even small periodic driving forces can produce large

amplitude oscillations.

Resonance occurs when a structure is able to store and transfer energy between two or more different storage

modes (such as kinetic energy and potential energy in the case of a pendulum). However, there are some losses

from cycle to cycle, called damping. When damping is small, the resonant frequency is approximately equal to

the natural frequency of the structure, which is a frequency of unforced vibrations. Some structures have multi-

ple, distinct, resonant frequencies.

Resonance phenomena occur with all types of vibrations or waves. The resonance structures demonstrate

mechanical resonance. Unlike a standing wave on a string vibrating between two rods which has nodes at both

ends, the resonance beam has a node at one end and an antinode at the other.

Resonance Beam

Build a resonance beam using five #5 I-beams and four Straight Connectors (SC).

Use four Flat Connectors, four #2 I-beams, and a Full Round Connector to build a

base for the beam as shown below.

Place slotted masses (such as those from the ME-7566 Large Slotted Mass Ses) on top of the Flat Connectors to

stabilize the resonance beam.

Mount a Mechanical Wave Driver (SF-9324) on a support rod so that its drive post is horizontal. Align the driver

so that you can attach the drive post to the middle of the first #5 I-beam of the resonance beam. One way to

attach the drive post to the I-beam is to loop a piece of yellow cord through the hole in the middle of the I-beam

and then through the hole on the accessory banana plug of the driver. Another way to attach the drive post is to

mount a Sliding Connector to the middle of the I-beam. Loop a piece of yellow cord through the Cord Clip and

attach the Cord Clip to the Sliding Connector. Connect the cord to the drive post.

You can control the Mechanical Wave Driver with a PI-8127 Function Generator, or with a PASCO Interface and

Power Amplifier.
