Figure 7.14. Horizontal test unit with rocking load. 1. base; 2. inclined plate; 3. rocking load; 4. trolley. The basic parameters of the test unit with the rocking load (mass of trolley moment of inertia of the load and radius vector ) are determined from the condition of equality of momenta and the coefficients which define the relative trajectories for the initial scheme (two-dimensional impact of two solid bodies, see section 7.7.2) and models with a rocking load. The values of these parameters depend on the angle between the longitudinal axes of the bodies If one defines the parameters of the test unit for that is, if one uses the following correlations: and keeps them unchanged, then for an error appears in the reproduction of the equivalent mass and the relative trajectories compared with the initial
