Problem 4-40: In the design of couplers-the hook- like linking mechanisms-between the cars of a train, extreme situations are often considered to assess lim- iting requirements. Suppose a locomotive of mass 30,000 kg pulls 80 cars each of mass 30,000 kg. At an acceleration of 0.5 m/s², how much load is trans- ferred by the coupler between the locomotive and the first car: between the 79th and 80th cars?
