P6-4

In the 4-bar linkage with dimensions shown above (in mm) the crank is 45 degrees from horizontal fixed frame link and has a CCW angular velocity of 0.deltadeltadeltaderltarad/s and CCW angular acceleration of 2.deltadeltarad/s^2. Determine the angular velocity and angular acceleration of rocker. Note that the crank angle and link lengths are sufficient information to uniquely determine the location of all links.
