Good luck KD!

Was taking a look at your tutorial.. And seriously, it's not simple! This is wat i learned only last semester, and i fucked up the module (didn't even manage to do any of the exam questions!)

It's a rigid body, so you have to use kinematics for rigid bodies
You have to use relative frames.
Draw 2 axes, one for the driving part, and another for the driven part.
find out how e 2 axes are related.
Use the general equation



Ok, the first thing to do now is DON'T GIVE UP!
Look thru the equation and give it some time..
All the superscript F are Fixed frames. Rs are Relative Frames.
For the subscripts, Q refers to the point you're interested in. P refers to a point on the driving body.
the normal fonts refers to the usual things, radius, omega, alpha, velocity, acceleration

If they expect you to do this question, then you should at least have come across this equation.
If not, well..... *salute* Good luck soldier!
