The bending can be mounted vertically (standing or hanging) or horizontally into the frame by varying the free clamping length or moving additional weights, the natural frequency of the bar is changed. The additionally required sensor supply module processes the signal for its display on an oscilloscope (not supplied). The bar is deflected manually to start damped vibrations. A non-contact position sensor measures the corresponding amplitudes.

Using the Set of Piers 3 Profiles accessory, it is possible to perform experiments on pillars in rivers in the Modular Flow Channel. The experimental set-up is made of PVC and is attached to the base of the channel using bolts. Pointed, rounded and flat flow splitters are provided; these can be combined as required. The unit contains 3 different, separable pillar types, 2 of each type of pillar fitted to the base plate represent the complete experimental set-up ready for installation in the flow channel.
