Question

A locomotive is running at a constant speed of 100 km/hr.The diameter of driving wheel is 1.8 m the stroke of the piston of the steam engine cylinder of the locomotive is 600 mm. Find the centrifugal acceleration of the crank pin relative to the engine frame

Answer 1

100kph = 27.78m/s

Wheel circumference = 1.8×π = 5.65m

27.78m/s ÷ 5.65m = 4.91 revolutions/second

Knowing the wheel speed does not determine engine speed

without gearing. I will solve for direct drive and you can apply the

reduction factors.

Angular acceleration = v²/r = (4.91m/s)²/.6m = 40.216 m/s²
