And for this sort of linkage the Euler-Bernoulli equation are more complicated. Not only we have the previous two terms, which was there in the rotary link, but we have, what are so called, convective terms which relate the coupling between the rigid motion of the link and the flexible motion of the link. Likewise in the previous case we have four boundary conditions at the beginning and at the end of this link. Now, these partial differential equations can be solved in several ways.
