Q) A SINGLE CYLINDER HORIZONTAL ENGINE RUNS AT 120 R.P.M. THE LENGTH OF STROKE IS 400 MM. THE MASS OF THE REVOLVING PARTS ASSUMED CONCENTRATED AT THE CRANK PIN IS 100 KG AND MASS OF RECIPROCATING PARTS IS 150 KG. DETERMINE THE MAGNITUDE OF THE BALANCING MASS REQUIRED TO BE PLACED OPPOSITE TO THE CRANK AT A RADIUS OF 150 MM WHICH IS EQUIVALENT TO ALL THE REVOLVING AND 2/3RD OF THE RECIPROCATING MASSES. F THE CRANK TURNS 80° FROM THE INNER DEAD CENTRE, FIND THE MAGNITUDE OF THE UNBALANCED FORCE DUE TO THE BALANCING MASS.

Question
Q) A SINGLE CYLINDER HORIZONTAL ENGINE
RUNS AT 12O R.P.M. THE LENGTH OF STROKE IS
400 MM. THE MASS OF THE REVOLVING PARTS
ASSUMED CONCENTRATED AT THE CRANK PIN
IS 100 KG AND MASS OF RECIPROCATING
PARTS IS 150 KG. DETERMINE THE MAGNITUDE
OF THE BALANCING MASS REQUIRED TO BE
PLACED OPPOSITE TO THE CRANK AT A
RADIUS OF 150 MM WHICH IS EQUIYALENT TO
ALL THE REVOLVING AND 2/3RD OF THE
RECIPROCATING MASSES. F THE CRANK
TURNS 80° FROM THE INNER DEAD CENTRE,
FIND THE MAGNITUDE OF THE UNBALANCED
FORCE DUE TO THE BALANCING MASS.
