Unformatted text preview: part of a fourbar loop that contains the frame as one of the members, it is not possible to analyze the linkage directly using the vector polygon approach. Solution: If the position of the linkage is known, a velocity solution can be achieved recognizing that all of the velocities in the linkage are linearly related to the velocity of the input member. Therefore, we can solve the velocity problem indirectly by first assuming the linkage to be driven by , rotating at 1 rad/ s in a specified direction. The velocity polygon is completed and the angular velocity of is found. C O C A O A 1.5 Example: 1) Position Analysis a) Changing AO A continuously to get the coupler’s curve b) With the given O C C position, getting the required linkage position. 2) Velocity Analysis 1.6 2) Velocity Analysis...
