Situate all the instantaneous centres:
Situate all the instantaneous centres for a mechanism illustrated in figure
Table of I. Cs
I12 I13 I14
I23 I24
I34
Solution
No. of I. Cs. = 6
The instantaneous centres I12 & I14 lie at infinity. I23 & I34 are at hinges O2 & O4 respectively. To find out I13 & I24 circle diagram may be utilized as in the case of above examples 4.1 & 4.2. I13 may be utilized to resolve velocity of a point on link 3.
