For the $3$Bar Inverted Crank Slider shown,

Starting with the position equation

$R=A{u}_{?},$ where $A$ is the rotation matrix

about the z axis and $u_{?}$ is a point on the

position vector, derive the velocity

equations in both algebraic and matrix

form to solve for ${}_3$ and $b^{}.$

What are the vector position and

velocity equations?

Your matrix equation must be in the

form $[,]\left[\begin{array}{c}{}_3\\ b^{}\end{array}\right]=[]$
