LINKWORK MECHANISM OF AN ACCELEROMETER

U-tube 1 of the chamber is filled with mercury, the level being at the same height in both branches. In measuring linear acceleration, the column of mercury in tube 1 is displaced by inertia, thereby displacing the water on top of the mercury. This forces a certain additional amount of water into one of the elastic tubes, 2 or 3. The deformation of these tubes, caused by the change in pressure, is…
