CRITICAL RADIUS OF INSULATING MATERIAL APPARATUS
It is well known fact that addition of insulation over a hot cylinder always
does not reduce the heat loss, because heat loss increases up to critical
radius. The 'DYNAMIC' apparatus consists of four test cylinders having
insulation of different thickness and a heater inside. Inside and outside
temperatures of insulation can be measured and by properly adjusting the
inputs to the heaters, it can be shown that heat loss ( i.e. input ) is
maximum for the test piece whose insulation thickness was near critical
radius. Thus the equipment demonstrates a very important and interesting
( No ! Don't misplace this with Critical Heat Flux - a boiling heat transfer apparatus. This is conduction heat transfer apparatus.)
UNIVERSAL VIBRATION APPARATUS IN MODULES
The Mechanical vibrations, near about 10 to 12 experiments are to be
conducted. The conventional system was to provide a common frame
to conduct all the experiments. The procedures was cumbersome and
time consuming to assemble and dismantle each experiment and
possessed lot of inconvenience. Also, vibrations of main frame itself
was a nuisance. To avoid this, we made the vibration apparatus in
three different modules, one each for torsional vibrations, pendulum
experiments and transverse vibrations. This has nearly eliminated the
procedure of assembly and dismantling of the experiments and secondly,
at a time three batches simultaneously can conduct the experiments.
Also, we are providing additional 12th experiment of Trifilar suspension.
So with 'DYNAMIC's Modular Universal Vibration Apparatus, conducting
vibration experiments has become very easy and quick.
EPICYCLIC GEAR TRAIN & HOLDING TORQUE APPARATUS
Epicyclic gear trains are widely used in industries and automobiles.But
their construction and operation is rarely seen by students. 'DYNAMIC'
has developed the apparatus which can show the construction and also
students can make the experiments with it. The gears trains is driven by
a motor. The sun gear drives two planet gears which mesh with an internal
gear. Either the internal gear or the planet gear carrier can be hold
stationery and input torque, output torque and holding torque can be
measured. Thus the student can have complete insight of the epicyclic
gear train with the apparatus.
