So recently I have finally managaed to complete the calibration process of my experiment despite a few problems on the way and I'm now well under way, getting some real data to analyse. Here are a few pictures to show you whats happening now in the lab!
This was just after the the sand went into the tank.
This is the plough in action today and works as follows:
- The trolley is pulled along the tank using a pulley system attached to a motor,
- The horizontal distance is recorded using another cable attached to the trolley which is electronically communicated to the computer interface.
- The magnitude of the velocity of the trolley is determined by the voltage input. This is controlled by the user.
- Finally, the depth achived is recoded using a spring loaded instrument, which electronically records the displacement as a voltage which can then be converted using the calibration.
