# Description

Solution of the D6 version 41 of teormeh of Manuals Targ SM 1988 (also coincides with the problem D8 Targ 1983). Check the condition to the task D6 (p. 56 in the training manual Targ SM): The mechanical system consists of the bodies 1, 2, 3, 4, 5, having a weight of P1, P2, P3, P4, P5, respectively; body systems are linked filaments wound on the stepped blocks 1 and 2 (Fig. D6.0, D6.9, Table. D6). A dash in the table columns, which are given weight, means that the relevant body is not included in (the figure does not depict), a zero in the columns of the table means that the body is considered weightless but in part (in the figure should be shown). For wheels, numbered 4, P4 - their total weight (the weight of a platform truck is not considered). The radii of stepped blocks 1 and 2 are, respectively: R1 = R, r1 = 0,8R; R2 = R, r2 = 0,4 R. In calculating the moments of inertia of the two units, wheels and rollers as homogeneous cylinder of radius R. In the system other than the gravity force acting force applied to the body F. 4 or 5 (if the body 5 is not included in , the force applied to a point in the trolley), and a pair of forces with the moment M1 and M2 are attached to blocks (for M <0 the direction opposite to the time shown in the figure). On thread portion indicated in the table under "Spring", including spring with stiffness coefficient s (for example, if the column should AB, AB is the portion of the spring, if the AD AD spring, etc.); initially the spring is not deformed. Create Lagrange equations for the system and to determine the frequency of them, and the period of oscillation, made of bodies as it moves.
