For a 4-bar linkage, $r_1 = 6$-cm, $r_2 = 2$-cm, $r_3 = 8$-cm, $r_4 = 10$-cm, $\theta_2 = 30$ degrees, $\omega_2$ is a constant angular velocity of 15 rad/s CW. $\theta_3 = 90.9$ degrees and $\theta_4 = 116$ degrees. The coupler in a ternary link with dimensions AB = 8 cm, AC = 3 cm and BC = 6 cm. Find $\alpha_3$, $\alpha_4$, $A_A$ and $A_C$. To find $A_C$, I suggest that you sketch the mechanism.

3. Buffers (From Buffer Handout) (a) (10 Points) You are to prepare 200 mL of an Acetic Acid (pKa= 4.75) / Sodium Acetate Buffer of pH = 4.700. You are given a solution of 3M Acetic Acid and a solution of 1 M Sodium Acetate. Assume that the molarity of the Sodium Acetate in the buffer is 0.20 M using the Henderson - Hasselbalch equation calculate the volumes of Acetic Acid, Sodium Acetate, and Distilled that would be required to make this buffer? (b) (10 Points) Transfer 100 mL of your Buffer from above and add enough of 1 M HCI to reduce the Acetate ion concentration by half. What is the new pH?
