Решение К1 Вариант 28 (рис. 2 усл. 8) термех Тарг 1988

Solution of the K1 version 28 to teormeh of Targa SM 1988 .. Conditions to the problem of kinematics section 1 (p. 19 in the training manual Targ SM): Point B moves in the plane xy (Fig. K1.0-K1.9, Table. K1, the trajectory of the figures shows probation). The law of motion defined by equations point: x = f1 (t), y = f2 (t), where x and y are expressed in inches, t - in seconds. Find the equation of the trajectory; at time t1 = 1 to determine the velocity and acceleration of the point, as well as its tangential acceleration and the radius of curvature at the corresponding point of the trajectory. Dependence x = f1 (t) labeled on the drawings, and the dependence y = f2 (t) is given in the Table. K1 (for Figs. 0-2 column 2 to Fig. 3-6 in column 3 for the Fig. 7-9 column 4).
