engineering recuitment UPPSC AE Mock Test 2024 Theory of Machines Balancing Balancing of Reciprocating Mass
The following data relate to a single-cylinder reciprocating engine: mass of reciprocating parts = 40 kg, mass of revolving parts = 30 kg at crank radius, speed = 150 rpm, stroke = 350 mm. If 60% of the reciprocating parts and all the revolving parts are to be balanced, what is the balance mass required at a radius of 320 mm ?
