now my problem is the drawbar remember it connects the train and the locomotive, will you find the tractive force in both locomotive and the train then find the difference between the two to get the pull or what should you do to get the drawbar pull

according to me the tractive force minus the resistive force minus the resistive force due inclination which is mgsigθ because it always act on the opposite direction which will equal to ma that is; F-R-mgsinθ=ma therefore; F=R+mgsinθ+ma where R will be the resistive force together with mgsinθ

where will the angle of inclination and the resistive force be used in that case

Homework Statement a locomotive of mass 20 tonnes hauls a train of mass 200 tonnes up an incline of 1 in 200. the resistive force for the locomotive and the train is 40 Newtons per tonne. the train accelerates from rest to 60km/h in 2km.determine; a) the tractive force of the locomotive b) the...
