Description
The
set up consists of heavy stainless steel disc mounted on a horizontal shaft,
rotated by a variable speed motor. The
rotor shaft is coupled to a motor mounted on a trunion frame having bearings
in a yoke frame, which is free to rotate about vertical axis. A weight pan on
other side of disc balances the weight of motor. Rotor disc can be move about three
axis. Torque can be applied by calculating
the weight and distance of weight from the center of rotor. The gyroscopic couple can be
determined.
SCOPE OF EXPERIMENTATIONS:
· Experimental justification
of the equation T = l w. wp for
calculating the gyroscopic couple by observation and measurement of results
for independent vibrations in applied
couple T and precession wp.
· To study the gyroscopic
effect of a rotating disc.
· Observation of gyroscopic
effect of rotating disc.
UTILITIES REQUIRED:
· Electric supply
o 230 V AC, Single Phase.
· Bench area
o 1m x 1m
· Tachometer to find out RPM
of disc.
