Using constraint equations find the relation between a_(1)"and" a_(2) |
|
Answer» Solution :Points 1,2,3 and 4 are movable . Let their dis-placements from a fixed line be `x_(1),x_(2),x_(3) "and" x_(4)` `x_(1)+x_(3)=l_(1)` `(x_(1)-x_(3))+(x_(4)-x_(3))=l_(2)` `(x_(1)-x_(4))+(x_(2)-x_(4))=l_(3)` On double differentiating with respect to time , we will get following three constraint RELATIONS :`a_(1)+a_(3)=0`....(i) `a_(1)+a_(4)-2a_(3)=0`....(ii) `a_(1)+a_(2)-2a_(4)=0`....(iii) Solving Eqs. (i), (ii), and(iii) we get `a_(2)=-7a_(1)` Which is desired RELATION between `a_(1) "and" a_(2)`
