Balancing of Rotating Masses

These flashcards cover key vocabulary and definitions related to the balancing of rotating masses.

Centrifugal Force

The force acting radially outwards on the axis of rotation of a shaft, given by the equation $F_c = mr heta^2$.

Dynamic Balance

A system of rotating masses is in dynamic balance when the resultant centrifugal force is zero ($ ext{ }oldsymbol{ ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ } ext{ }) and the resultant couple is also zero.

Mass-Arm Product

The product of mass and radius, which is proportional to the centrifugal force exerted by each mass in a rotating system.

Balancing Mass

A secondary mass introduced to counteract the centrifugal force produced by a primary mass in a rotating system.

Force Polygon

A graphical representation used to solve force balance problems in which the magnitudes and directions of the forces are represented as vectors.

Couple Polygon

A graphical method used to analyze the moments (couples) acting on a rotating system and to find the necessary balancing couples.

Static Balance

A condition where the rotating mass distribution is such that the net centrifugal forces and moments produce no movement in the system.

Centrifugal Pumps

Machines designed to move fluids by the conversion of rotational kinetic energy to hydrodynamic energy.

Graphical Method

A technique used to solve problems involving balancing masses or forces using graphical representations like force polygon and couple polygon.

Longitudinal Displacement

The axial displacement along the shaft axis, relevant in balancing rotating masses.
