Solution D1-97 (Figure D1.9 condition 7 S.M. Targ 1989)

The solution to problem D1-97 (Figure D1.9 condition 7 S.M. Targ 1989) is as follows. At the initial moment of time, a load of mass m receives an initial speed v0 at point A and begins to move in a curved pipe ABC, which is in a vertical plane. Pipe sections can either be both inclined, or one horizontal and the other inclined (Fig. D1.0 - D1.9, Table D1).

In section AB, in addition to the force of gravity, the load is acted upon by a constant force Q (its direction is indicated in the figures) and a resistance force of the medium R, which depends on the speed v of the load and is directed against the movement. In this case, the friction of the load on the pipe in section AB is not taken into account.

At point B, the load, without changing its speed, moves to the section BC of the pipe, where, in addition to the force of gravity, it is acted upon by the friction force (friction coefficient of the load on the pipe f = 0.2) and the variable force F, the projection of which Fx on the x axis given in the table.

Considering the load as a material point and knowing the distance AB = l or the time t1 of movement of the load from point A to point B, it is necessary to find the law of movement of the load in the section BC, that is, x = f(t), where x = BD.

Solution D1-97 describes the movement of a mass m in a curved pipe ABC located in a vertical plane. The load, having received an initial speed v0 at point A, moves along the section AB, in which, in addition to the force of gravity, it is acted upon by a constant force Q and a resistance force of the medium R, which depends on the speed of the load. At point B, the load moves to section BC, where it is acted upon by a friction force and a variable force F, the projection of which Fx on the x axis is given in the table. The coefficient of friction between the load and the pipe is 0.2.

To find the law of cargo movement on the aircraft section, i.e. x = f(t), where x = BD, it is necessary to know the distance AB = l or the time t1 of movement of the load from point A to point B.
