Part A A train consists of a 50 Mg engine and three cars, each having a mass of 25 Mg . If it takes 90 s for the train to increase its speed uniformly to 36 km/h, starting from rest, determine the force T, developed at the coupling between the engine E and the first car A. The wheels of the engine provide a resultant frictional tractive force F which gives the train forward motion, whereas the car wheels roll freely. Express your answer with the appropriate units. HA Value Units T = Submit Request Answer Figure • Part B 1 of 1 Also, determine F, acting on the engine wheels.(Figure 1) Express your answer with the appropriate units.

Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.
