2. You are doing a summer internship in a lab that studies muscular development using the model system \textit{C. elegans}. To identify genes involved in muscle development you have performed a genetic screen in which you have mutagenized worms and identified 9 mutants that have the \textquotedbl{}twitching\textquotedbl{} phenotype. To determine the number of genes you have in your mutant collection, you perform a complementation test and get the following results. + indicates that the double mutant is wild-type and tw indicates that the double mutant has the twitching phenotype.

What could be going on in mutant-10?

A uniform bar AB of length $L = 900 \text{ mm}$ and mass $m = 4 \text{ kg}$ is suspended from a fixed hinge C which is at a distance of $r$ from the center of mass as shown in the diagram. A horizontal force $P = 75 \text{ N}$ is applied at end B. The bar is at rest when the force is applied (i.e., the angular velocity at this instant is $\omega = 0$). Answer the following questions. Choose an appropriate coordinate system and show your work clearly. \begin{itemize} \item Assume that the bar has an unknown angular acceleration $(\alpha)$ at this instant of time. Determine the acceleration of the center of mass, G, of the bar at this instant as a function of $\alpha$. \item Draw a free body diagram and write out all required kinetics equations (i.e., sum of forces and sum of moments). \item Determine the distance $r$ for which the horizontal component of the reaction force at C is zero. \end{itemize}
