1.Adiabatic process Thermodynamics process in which no heat is transferred to or from thee system during the process. A reversible adiabatic process is called isentropic process. 2.Airfoil A streamlined form bounded principally by two flattened curves and whose length and width are very large in comparasion with thickness. 3Airfoil drag force: Force acting on the airfoil in the direction of motion represnets frictional forces. 4.Air rate Kilograms per second of airfloebrequired per net horse powrer developed . Also called Flow rate. 5.Angle of attack The angle of inclination of the non symmetrical airfoil with the direction of the undisturbed flow. 6.Angle of deviation The difference between the fluid angle at out and the blade angle at outlet.This may be positive or negative .Sometimes called Deviation. 7.Angle of incidence The difference between the fluid angle at inlet and the blade angle at inlet. 8.Aspect ratio of blade Ratio of blade height to blade...

Absolute motion Motion of a body in relation to some other body which is at rest. Acceleration Rate of change of velocity with respect to time, of a particle which is in motion.It is vector quantity. Addendum The radial distance from the pitch circle to the top of the tooth. Angular acceleration The time rate of change of angular velocity. Angular velocity The time rate of change of angular displacement of a point rotating about a fixed axis.Angular velocity of a machine part is often expressed in revolutions per minute. Arc of contact The arc traced out along the pitch circle while one pair of teeth of gear wheels is in contact . BEVEL GEARING – Gearing arrangement in which the axes of the shafts connected by gears intersect. CAM – A reciprocating, oscillating or rotating body which imparts reciprocating or oscillating motion to a second body, called the FOLLOWER with which it is in contact.  CAM PROFILE – The surface profile of the cam t...
