Answer to Question #298798 in Mechanical Engineering for axel

Question

In a slider crank mechanism the length of the crank OB is (174)mm and length of the connecting rod is (549)mm. The center of gravity G of the connecting rod is (324)mm from the slider A. crank speed is (574)rpm clockwise. When the crank has turned 45 deg. From the inner dead center

. Determine (using both relative velocity method and Instantaneous center method)

1. Velocity of the slider

2. Velocity of point G

3. Angular velocity of the connecting rod AB

Answer 1

To determine the velocities of different points on links of a mechanism for a given input motion. Determination of the motion characteristics of links in a mechanism is required for the force analysis • • Velocities of links and of points of mechanism Velocities of links and of points of mechanism can be determined by different methods. 1. Relative velocity method or velocity polygon method 1 2. Instantaneous center method.

Instantaneous Center of Velocity (ICV): Any point on a rigid body or on its extension that has zero velocity is called the Instantaneous Center of Velocity of the body.
