Theory of Machine
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)

m.ω².r sinθ
(1 - c).m.ω².r (cosθ - sinθ)
m.ω².r cosθ
m.ω².r (cosθ - sinθ)
