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: \[ \begin{array}{l} v_{C}=120 \mathrm{~mm} / \mathrm{s} \downarrow \\ y_{D}-\left(y_{D}\right)_{0}=125 \mathrm{~mm} \uparrow \end{array} \]

In the realm of theoretical mechanics, consider a situation where all materials exhibit perfect elasticity, returning to their original shape regardless of the magnitude of deformation. Discuss the implications for stress-strain relationships, Hooke's law, and the theory of elasticity. How would this affect the design and analysis of mechanical components like springs, beams, and structures? Explore the theoretical changes required in failure theories, fatigue analysis, and safety factors. Evaluate the potential benefits and challenges of such a hypothetical material property in mechanical engineering. \
