Indicator,water level,audible,100m

Water level depth indicator, battery powered (3 x 1.5 V, included and easily replaceable), for use in boreholes to a maximum depth of 100 metres.
A stainless-steel probe is securely fastened to the free end of the cable and the cable with probe is attached to a cable winding reel. Measurements are taken by slowly lowering the cable with probe down the borehole until the probe comes in contact with the water. 
The water level indicator consists of a flat, two cores, heavy duty cable calibrated in metres and centimetres on one side.
The unit is also equipped with an optical (light) signal that switches on upon contact of the probe with water. On contact with the water, the unit emits a high frequency audible signal, and the user can then take a depth reading from the calibrated cable.

Bending Test Plastic Deformation

Mechanical stress, to which design elements are generally exposed, generates stresses in the affected component or the material. The component does not return fully to its original form after the deformation, resulting in a change of shape. If these stresses are too large, there is plastic deformation of the material in addition to the elastic, reversible deformation.

Features:
Plot loadextension diagrams.
Observe and determine the transition from elastic to plastic deformation.

Learning Objectives And Experiments:
Load on a beam with a point load
Demonstrate the invalidity of the superposition principle in the plastic region
Compare the load and relief curves
Plot a loadextension diagram and determine the nonlinear behaviour.

The Study Of Three Phase Synchronous Machines

Among three-phase power supply the synchronous machines are widely used and they called so because the speed of the rotor of these machines are the same as the rotating magnetic field. They are commonly used as generators especially for large power systems, such as turbine and hydroelectric generators in the grid power supply. Because the rotor speed is proportional to the frequency of excitation,synchronous motors can be used in situations where constant speed drive is required. Since the reactive power generated by a synchronous machine can be adjusted by controlling the magnitude of the rotor field current, unloaded synchronous machines are also often installed in power systems solely for power factor correction or for control of reactive kVA flow. Their construction is almost similar to that a three-phase induction motor except the fact that the rotor is given DC supply.
