Solution K3-76 (Figure K3.7 condition 6 S.M. Targ 1989)

The presented solution relates to problem K3-76 from the textbook by S.M. Targa 1989 and describes the operation of a flat mechanism consisting of rods 1, 2, 3, 4 and a slider B or E (Figure KZ.0 - K3.7) or of rods 1, 2, 3 and sliders B and E (Figures K3 .8, K3.9), connected to each other and to fixed supports O1, O2 by hinges. Point D is in the middle of the rod AB, and the lengths of the rods are l1 = 0.4 m, l2 = 1.2 m, l3 = 1.4 m and l4 = 0.6 m. The position of the mechanism is determined by the angles α, β, γ, φ, θ, the values ​​of which and other quantities are indicated in the tables KZa (for Figures 0-4) and KZb (for Figures 5-9). The arc arrows in the figures show how the corresponding angles should be laid when constructing a drawing of the mechanism: clockwise or counterclockwise. For example, angle γ in Figure 8 should be plotted clockwise from point DB, and in Figure 9 - counterclockwise, etc. To start constructing a drawing, you need to select a rod, the direction of which is determined by the angle α, and a slider with guides depict as shown in the example of a short circuit (see figure KZb). The values ​​indicated in the tables in the “Find” columns must be determined. Angular velocity and angular acceleration should be considered directed counterclockwise, and velocity vB and acceleration aB should be considered directed from point B to b (in Figures 5-9).

Solution K3-76 is a mechanism consisting of flat rods 1, 2, 3, 4 and a slider B or E, connected by hinges to each other and to fixed supports O1, O2. Point D is in the middle of rod AB. 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.

To construct a drawing of a mechanism, you need to start with a rod, the direction of which is determined by the angle α. The slider with guides should be depicted as in the KZ example (see Fig. KZb). The arc arrows in the figures show how, when constructing a drawing of a mechanism, the corresponding angles should be laid out: clockwise or counterclockwise.

The tables indicate the values ​​of angles and other specified quantities, as well as the quantities that need to be determined in the "Find" columns. To calculate these values, it is necessary to take into account the given angular velocity and angular acceleration, which are considered to be directed counterclockwise, as well as the given speed vB and acceleration aB, which refer to point B and are directed to b in Figures 5-9.
