The tractive force in a locomotive with two cylinders is given by (where c = Fraction of reciprocating parts per cylinder, m = Mass of reciprocating parts, ω = Angular speed of crank, r = Radius of crank, and θ = Angle of inclination of crank to the line of stroke)

  • Am.ω².r cosθ
  • Bc.m.ω².r sinθ
  • C(1 - c).m.ω².r (cosθ - sinθ)
  • Dm.ω².r (cosθ - sinθ)
Correct Answer : (C)

(1 - c).m.ω².r (cosθ - sinθ)
