Solution D1 Option 44 (Fig. 4 cond. 4) termehu Targ 1988

The solution to the problem D1 Option 44 termehu of Taskbook Targ SM 1988 .. Conditions to the problem of the dynamics section 1 (p. 32 in the training manual Targ SM): D Load mass m, received at the point and the initial velocity v0, moving in a curved tube ABC, located in the vertical plane; pipe sections, or both inclined, or one horizontal and one inclined (Fig. D1.0, D1.9 Table. D1). Figure AB cargo except gravity constant force Q (its direction is shown in the figures) and the power of the medium resistance R, depending on the speed of the load v (directed against the motion). At the point in the load, without changing the values \u200b\u200bof its speed, the sun moves to the area of \u200b\u200bthe pipe, where it except gravity acting variable force F, whose projection Fx on the x-axis is given in the table. Considering the load of the material point and knowing the distance AB = l or the time t1 the movement of cargo from point A to point B. Find the traffic load on the section BC, ie x = f (t), where x = BD. Friction load of pipe neglected.
