Anybody out there have a theorem for determining a motor's stall torque and no load speed using a flywheel of a known mass and measuring current draw? I'd probably have to time the acceleration as well, but it seems as if this could be done, I just need a little help with the theory and equations. Thanks.

I know obout B.M. Birla Scienc Center at Hyderabad,
A.P., India. It has conducted a symposium on "Science
and Technology in ancient India" in December 1990. Many
topics ancient Indian aeronautics were discussed. The
Vimanika Prakaranam in Vimana Vignana deals with
instruments like Guha Garbha Darsha Yantra which can
locate objects hidden underground from an aircraft. a
semiconductor ferrite named Chumbaka radiates microwave
signals and detects hidden objects.

The B.M. Birla Scienc Center has been doing active
active research in finding scientific content in Vedas
and Puranas. The Center has deciphered a number of new
materials from Amsu Bodhini. These materials comprise
of glasses with special effects and metallic alloys
with rare properties - many of them have extraordinary
properties unknown to modern technology.
