Targ SM 1989 D10 B74 solution of the problem (Fig. 7usl. 4)

The task of teormeh of Targa SM 1989 D10 Option 74. Conditions to task Dynamics 10 (Full condition on page 91): The mechanical system consists of a homogeneous step pulleys 1 and 2 wrapped yarns, 3-6 cargo attached to these threads and weightless unit (Fig. D10.0 - D10.9, Table. D10). The system moves in a vertical plane under the action of gravity forces and couples a torque M applied to one of the pulleys. Radii stages pulley 1 are: R1 = 0,2 m, r1 - 0,1 m and the pulley 2 - R2 = 0,3 m, r2 = 0,15 m; of their radii of gyration about the axes of rotation are respectively p1 = 0,1 m and p2 = 0,2 m. Neglecting friction, determine the acceleration of the load, having a greater weight; weights P1, ..., P6 and pulleys goods specified in the table in Newtons. Loads, the weight of which is equal to zero, the figure does not represent the (pulleys 1 and 2 depict always as part of the system).

I would be very grateful if, after successful completion of the work you leave positive feedback. Believe me, for me it is very important.
Thanks in advance.
