, on the wheels; the mean effective steam force,P, acting both upon the piston and the cylinder head;the tractive force, T; and the adhesion, F, betweenthe drivers and the rails. This adhesion is a friction 40 APPLIED STATICS force which prevents the drivers from slipping upon therails. This… … To avoid complications consider the locomotive run-ning at a constant velocity so that its kinetic energydoes not change. Under this condition the work doneby all the forces acting upon it as a free body must sumto zero. As a convenient displacement consider one stroke of thepiston or one-half a…
