Objective:

To study the vibration characteristics of an aluminium cantilever beam using piezoelectric-ceramic (PZT) sensor.

Apparatus Used:

1. Digital multimeter

2. Concrete blocks

3. Hammer

4. PZT patch

5. Aluminium cantilever

Step-1: (a) Click on add button to bring aluminium cantilever. Step-1: (b) Click on add button to bring concrete block. Step-1: (c) Click on aluminium cantilever to place it on the concrete block. Step-1: (d) Click on add button to bring another concrete block. Step-1: (e) Click on concrete block to place it on the aluminium cantilever. Step-1: (f) Click on add button to bring epoxy. Step-1: (g) Click on brush to apply epoxy on the aluminium cantilever. Step-1: (h) Click on add button to bring PZT patch. Step-1: (i) Click on PZT patch to fix it on the aluminium cantilever.

Step-2: (a) Click on add button to bring soldering iron. Step-2: (b) Click on add button to bring wires. Step-2: (c) Click on red wire to place it on the PZT patch. Step-2: (d) Click on black wire to place it on the PZT patch. Step-2: (e) Click on PZT patch for zoom view. Step-2: (f) Click on soldering iron for soldering. Step-2: (g) Click on soldering iron to bring it back. Step-2: (h) Click on add button to bring hammer. Step-2: (i) Click on add button to bring digital multimeter. Step-2: (j) Click on black clip to attach wire with PZT patch's wire. Step-2: (k) Click on red clip to attach wire with PZT patch's wire. Step-2: (l) Switch on the power button of digital multimeter. Step-2: (m) Click on hammer button to start animation. Step-2: (n) Click on stop button to stop animation.
