Meeting the challenge of K3 Option 41 Reshebnik on theoretical mechanics to Taskbook Targ SM 1982.
Subject K3 tasks - Study of plane rigid body motion.
Check the condition of the problem to K3 (Page 38-43, zadachnik Targ SM 1982):
Flat mechanism consists of rods 1, 2, 3, 4 and slider B or E (Fig KZ.0 -. K3.7) or bars 1, 2, 3, and slides in and E (Fig K3.8, K3,.. 9) connected to each other and with fixed bearings O1, O2 hinges; the point D is in the middle of the rod AB. The lengths of the rods are, respectively, 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 predetermined values ​​are listed in Table. ACA (for Figs. 0-4) or in the Table. HSC (for Figure 5-9.) in this Table. ACA ω1 and ω4 - constant.
Determine the values ​​shown in the tables in the columns of "Find."
