Examination D4 B24 (Figure 2 conv 4) termehu Targ 89g

The task of termehu of Targa SM D4 B24. Conditions of the problem D4: The mechanical system consists of a rectangular vertical plate 1 mass m1 = 18 kg, moving along the horizontal rails and cargo D mass m2 = 6 kg (Fig. D4.0 - D4.9, Table. D4). At time t0 = 0 when the speed of the plate u0 = 2 m / s, the load under the action of internal forces begins to move along the chute plate. Fig. 0-3 KE chute straight and cargo movement distance s = AD varies as s = f1 (t), as shown in Fig. 4-9 chute - a circle of radius R = 0,8 m and the motion load angle phi = ∟AC1D varies as f = f2 (t). Table. D4 depending on the given separately for rice. 0 and 1 for Fig. 2 and 3, and so on. G., Where s is expressed in meters phi - radians »t - in seconds. Considering the load of the material point and ignoring all resistances, determine the dependence of u = f (t), t. E. The speed of the plate as a function of time.
