Lab Manual | Gyroscopic Effect

November 14th, 2009 No comments

AIM :- To study gyroscopic effects through models.

APPARATUS USED:- Models of Aero plane and ship.

THEORY :- The earliest observation and studies on gyroscopic phenomenon carried out during Newton’s time. These were made in the context of the motion of our planet which in effect in a massive gyroscopic. The credit of the mathematical foundation of the principles of gyroscopic motion goes to Euler who derived at set of dynamic equation relating applied mechanics and moment inertia, angular acceleration and angular velocity in many machines, the rotary components are forced to turn about their axis other than their own axis of rotation and gyroscopic effects are thus setup. The gyroscopes are used in ships to minimize the rolling & pitching effects of water.

Lab Manual | Watt and Porter Governor

November 14th, 2009 No comments

AIM :-To perform experiment on Watt and Porter Governors to prepare performance characteristic Curves, and to find stability & sensitivity.

APPARATUS USED:- Watt and Porter Governors.

INTRODUCTION & THEORY :- The function of a governor is to regulate the mean speed of an engine, when there are variations in the load e.g. when the load on an engine increases, its speed decreases, therefore it becomes necessary to increase the supply of working fluid. When the load on the engine decreases, its speed increases and thus less working fluid is required. The governor automatically controls the supply of working fluid to the engine with the varying load conditions and keeps the mean speed within certain limits.
