Decision D4 Option 41 (Fig. 4 conv. 1) termehu Targ 1988

Solution of the problem D4 Option 41 on the theoretical mechanics of the problem book Targ SM 1988. Conditions of the problem D4 (p. 48 in the training manual Targ SM) Vertical shaft AK (fig. D4.0, D4.9, Table. D4), rotating at a constant angular velocity ω = 10 s-1, is fixed to glide the point A and the cylindrical bearing at the point indicated in Table. D4 in column 2 (AB = BD = DE = EK = b). Rigidly secured to the shaft rod 1 is weightless length l1 = 0,4 m with a point mass m1 = 6 kg at the end of the rod 2 and a uniform length l2 = 0,6 m with a mass m2 = 4 kg; both bars lie in one plane. The attachment points to the shaft rods are indicated in the table in columns 3 and 4, and the angles α and β - in columns 5 and 6. Disregarding the weight of the shaft, the thrust bearing and to determine the reaction of the bearing. When the final tally to take b = 0,4 m.
