# Thread: How to design a Linkage let one point go line or a approximate line?

1. ## How to design a Linkage let one point go line or a approximate line?

no much load, just need a approximate line moving for 2 - 3 inches.
Thanks

2. 2 - 3 inches approximate line moving

3. It would be simple. If you make a circle and put another circle inside of it with a radius equal to R/2 and join them with gears to provide rotation speed by a rate of 2 to one and select a point on the smaller circle you find it with linear motion. If you have any more questions let me know.

4. Designing 4-Bar Linkages

Step 1: Draw Coupler in its Initial and Final Positions.
Step 2: Draw Arcs. Draw arcs from each mounting point on the output bar.
Step 3: Draw Locus Lines. Draw a pair of lines, one connecting the intersections of each pair of arcs.
Step 4: Draw Connecting Bars.
