Given that $\mathrm{L}=7.8\mathrm{m},\mathrm{r}=1.4\mathrm{m},\mathrm{d}=1.8\mathrm{m}$ and ${?}_{AB}=8.9\mathrm{rad}/\mathrm{s}$ What is the $\hat{k}$ component of the angular velocity of Link $\mathrm{BC}$ (in $\mathrm{rad}/\mathrm{s})$ ? Answer. What is the $\hat{k}$ component of the angular velocity of the wheel? Answer. What is the $\hat{k}$ component of the angular acceleration of Link BC (in $\mathrm{rad}/{\mathrm{s}}^2$ )? Answer: Given: $A$ mechanism is made up of links $AB,BC$ and a wheel pinned to $BC$ at the wheel's center $C$. The wheel rolls without slipping on a horizontal surface. Link $AB$ rotates counterclockwise with a constant rate of ${?}_{AB}$. At the instant shown, link $AB$ is vertical. Find: At this position (a) Determine the angular velocities of links BC and the wheel. Write your answers as vectors. (b) Determine the angular accelerations of links $\mathrm{BC}$ and the wheel. Write your answers as vectors. (The following questions will ask you to give certain numeric answers based on the work above). What is the $\hat{k}$ component of the angular acceleration of the wheel? Answer:
