Question

Please use a drawn example to demonstrate the purpose and steps of a 3 position synthesis with pre- assigned pivoting points of the linkage mechanism.

Answer 1

please a drawn onangle to demonstrate the purpose amo steps of a 3 . position synthesis with pre-assigned phosting points of the linkage mechaum det and having use congides a with centre. A three cine from center to circle B E AC AB, AD', and AD shown in the figure. B, A LA LOAD' 540 LBADE 90° LEAD:121.96 D A AF is re link poin A and F. So this is the method of thesis for example we take four bar mechanism les Suppose AD' AB AE are three position of Crank then what would be sue position of other links in the mechaners. to know about this wc consider the process as syurther's Now do we join by taking as showin below fig. steps as follown and draw circle radius BF and EF BF and Ef E D A

Gr! bisector 1, bisec tora. Now Follow the steps. After draw the circles take you a point on 1st circle as G. as mowin ig above. and Gi in and circle. Then join and make two new lines D'er and GG!! Маке two perpendicular bisector on the lines GG! and Digi wherever the bisedor intersect there we and sys thesis is done. A FPD' ar 4. abar tin mechanis by о 3 point cynthesis. get point we get
