9.4.9 To determine instantaneous

Solution to problem 9.4.9 from the collection of Kepe O.?. consists in determining the instantaneous angular velocity of the connecting rod AB for a given position of the mechanism. To do this, you need to know the length of the connecting rod BD, the speed of point B (vB) and the projection of the speed vector of point D onto the Ox axis (vDx). Using these data, it is possible to calculate the value of the instantaneous angular velocity of the connecting rod AB. The answer to the problem is 2.4.

The product is the solution to problem 9.4.9 from the collection of Kepe O.?. To solve the problem, it is necessary to determine the instantaneous angular velocity of the connecting rod AB at a given position of the mechanism. It is known that point B has a speed vB = 0.4 m/s, the length of the connecting rod BD = 0.5 m, and the velocity vector of point D on the Ox axis has a projection vDx = 0.2 m/s. The answer to the problem is the value of the instantaneous angular velocity of the connecting rod AB, which is equal to 2.4.
