Solution K3-90 (Figure K3.9 condition 0 S.M. Targ 1989)

The presented mechanism, designated as Solution K3-90 (Figure K3.9 condition 0 S.M. Targ 1989), is flat and consists of rods 1, 2, 3, 4, as well as a slider B or E (see Fig. KZ.0 - K3.7) or rods 1, 2, 3 and sliders B and E (see Fig. K3.8, K3.9), which are connected to each other and to fixed supports O1, O2 by hinges. In the middle of rod AB there is point D. The lengths of the rods are: l1 = 0.4 m, l2 = 1.2 m, l3 = 1.4 m, l4 = 0.6 m. The position of the mechanism is determined by the angles α, β, γ, φ, θ. The values ​​of these angles and other specified quantities are given in table. Short circuit (for Fig. 0-4) or in table. KZb (for Fig. 5-9). In table Short circuit ω1 and ω4 are constant values. You must determine the values ​​listed in the tables in the Find columns. The arc arrows in the figures indicate how, when constructing a drawing of a mechanism, the corresponding angles should be plotted: clockwise or counterclockwise (for example, angle γ in Fig. 8 should be plotted from DB clockwise, and in Fig. 9 - counterclockwise arrows, etc.).

When constructing a drawing, you must start with a rod, the direction of which is determined by the angle α. For greater clarity, the slider with guides should be depicted as shown in the example of a short circuit (see Fig. KZb). The angular velocity and angular acceleration specified in the task should be considered directed counterclockwise, and the given velocity vB and acceleration aB - from point B to b (in Fig. 5-9).
