**DISCUSSION THREAD**

Any questions??

*Four-step plan:*

* Step 1* - FBD: Draw a free body diagram of the bar.

* Step 2* - Kinetics: Write down the Newton/Euler equations for the sphere. Since there is no fixed point on the bar, choose the center of mass for your moment equation

* Step 3* - Use the rigid body kinematics equation for relating the accelerations of points A and B on the bar:

**a**_{B} = **a**_{A} + **α** x **r**_{B/A} - ω^{2} **r**_{B/A}

followed by relating the acceleration of B to the acceleration of the bar's center of mass, G:

**a**_{G} = **a**_{B} + **α** x **r**_{G/B} - ω^{2} **r**_{G/B}

* Step 4* - Solve
