Free Vibration of Bar Apparatus Model 048
Free Vibration of Bar Apparatus Model 048
The bending bar in Sci-tech Free Vibration of a Bar Apparatus Model MT 048 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 bar is deflected manually to start damped vibrations. A non-contact position sensor measures the corresponding amplitudes. The signal can be displayed on an inter-laboratory oscilloscope.
| Size: | 80cm x 40cm x 120cm (LxWxH) |
| Weight: | 15 kg |
