Question

The link shown in Fig. 16-14g is guided by two blocks at A and B, which move in the fixed slots. If the velocity of A is 2 m/s downward, determine the velocity of B at the instant $\theta = 45^\circ$. SOLUTION I (VECTOR ANALYSIS) Kinematic Diagram. Since points A and B are restricted to move along the fixed slots and $v_A$ is directed downward, then velocity $v_B$ must be directed horizontally to the right. Fig. 16-146. This motion causes the link to rotate counterclockwise; that is, by the right-hand rule the angular velocity $\omega$ is directed outward, perpendicular to the plane of motion. Velocity Equation. Expressing each of the vectors in Fig. 16-146 in terms of their i, j, & k components and applying Eq. 16-16 to A, the base
