1. The Crank 2 (shown in Figure 1) rotates with a constant angular velocity of $60\mathrm{rad}/\mathrm{s}$ (Counter Closed Wise), Using analytical method a) Obtain the angular velocity of link3 and velocity of point B, (7 Points) b) Obtain angular acceleration of the link 3 and acceleration of point B. (8 Points) (Hint: Link 4 slider oscillates about the fixed link, while the link 3 slides inside the link 4) (15 Points) Figure 1: $R_{AO2}=75\mathrm{mm},R_{BA}=400\mathrm{mm}$, and $R_{O4O2}=125\mathrm{mm}$
