Chapter 3, Problem 16P

Consider again the one-link planar robot shown in Fig. P3.14. Determine the length I and angle $\theta$ if the tip of the robot is located a the following points $P\left(x,y\right)$.

1. $P\left(x,y\right)=\left(3,4\right)\text{ in}\text{.}$ $P\left(x,y\right)=\left(-4,3\right)\text{ in}\text{.}$ $P\left(x,y\right)=\left(-3,-3\right)\text{ in}\text{.}$ $P\left(x,y\right)=\left(5,-4\right)\text{ in}\text{.}$
