# Description

The task of teormeh of Targa SM 1989 D10 Option 31. 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).
