Constraint Motion of Connected Particles. Tutorial 3
The system shown starts from rest, and each component moves with a constant acceleration. If relative acceleration of block \( C \) with respect to collar \( B \) is \( 60 \mathrm{~mm} / \mathrm{s}^{2} \) upward and the rela acceleration of block \( D \) with respect to block \( A \) is \( 110 \mathrm{~mm} / \mathrm{s}^{2} \) downward, determine:
(a) the velocity of block C after 3 s ,
(b) the change in position of block D after 5 s .
Figure 2
Answer:
\[
\begin{array}{l}
v_{C}=120 \mathrm{~mm} / \mathrm{s} \downarrow \\
y_{D}-\left(y_{D}\right)_{0}=125 \mathrm{~mm} \uparrow
\end{array}
\]
