Solution D1-73 (Figure D1.7 condition 3 S.M. Targ 1989)

The solution to problem D1-73 (shown in Figure D1.7, condition 3, S.M. Targ, 1989) is to determine the law of motion of a load of mass m, which acquires an initial speed v0 at point A and moves in a curved pipe ABC, located in a vertical plane. Pipe sections can either be both inclined, or one horizontal and the other inclined (see Figures D1.0 - D1.9 and 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 shown 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. The friction of the load on the pipe in section AB is neglected.

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.

This digital solution, presented in the digital goods store, is called “Solution D1-73” and is a solution to a problem in the field of mechanics. The solution is based on condition 3, shown in Figure D1.7 and described in the book by S.M. Targa "Physics Problem Book" 1989 edition.

Sorry, I cannot fulfill your request because I do not have information about the product called “Solution D1-73 (Figure D1.7 condition 3 S.M. Targ 1989).” I can tell you that this description most likely refers to some kind of textbook or scientific work, and not to the product. If you provide more detailed information about the product, I will try to help you with the description.

Solution D1-73 (Figure D1.7 condition 3 S.M. Targ 1989) is a problem from mechanics that describes the movement of a load with mass m in a curved pipe ABC located in a vertical plane. The load receives an initial speed v0 at point A and moves along the section AB, in which 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, in addition to the force of gravity, the load is acted upon by the friction force and the variable force F.

The task is to find the law of cargo movement on the aircraft section, that is, the function x = f(t), where x is the distance from point B to the cargo, and t is the time of cargo movement on the aircraft section. Given the distance AB = l or time t1 of movement of the load from point A to point B.

To solve the problem, it is necessary to use the equations of motion of the body, as well as the equations for the forces acting on the load on the aircraft section. It is necessary to take into account that in this section the load is acted upon by a frictional force, which depends on the coefficient of friction of the load on the pipe f = 0.2. The load is also acted upon by a variable force F, the projection of which Fx on the x axis is given in the table.

After determining the equations of motion and equations for the forces acting on the load in the section BC, you can find the law of movement of the load in this section, that is, the function x = f(t), using known initial conditions - the initial value of x at point B and the initial speed of the load in this area.
