# Description

The solution to the problem K2 Option 50 termehu of Taskbook Targ SM 1988 .. Conditions to the problem of kinematics section 2 (p. 22 in the training manual Targ SM): Flat mechanism consists of rods 1 - 4 and slider B, connected to each other and with fixed bearings O1 and O2 hinges (Figure . K2.0 K2.9-). Rod length: l1 = 0,4 m, l2 = 1,2 m, l3 = 1,4 m, l4 = 0,8 m. The position of the mechanism is determined by the angles a, b, γ, phi, theta, which together with other values are given in Table. K2. Point D in all figures and the point K in Fig. K2.7, K2.9 mid respective rod. Determine the values \u200b\u200bshown in the table under "Find." Find the acceleration of the point A aA rod 1 when the rod 1 is in a given time angular acceleration ε1 = 10 with 2-arc arrows in the figures show how the construction of the drawing should be delayed corresponding angles, i.e. during or counterclockwise (for example, the angle γ in Fig. 1 should be delayed from DE rod anticlockwise, and Fig. 2 - of the rod AE clockwise). Construction to begin drawing the rod, the direction of which is determined by the angle α; The slider and the guide for clarity to depict, as in Example R2 (see. Fig. R2). Given angular velocity count against clockwise, and set speed vB - from B to b.
