Calculating angular acceleration and translating to force

[swerider]

Hi there
I need some help in calculating the force created by angular motion.
I am designing a wheelie bar for my motorcycle and need to know what force the design must be able to handle.
I have attached a simple sketch of the design.
Taking into account; torque produced by the engine, bike-rider mass, position of center of mass...How would I go about calculating the force induced by angular motion about the rear wheel center as the wheelie bar hits the ground?
Thanks!

Do you want to know how much torque it would take to lift the front tire of your bike off the ground .
If you watch this video in like the first 10 minutes he talks about rotating cylinders and torque and moment of inertia , and relating angular acceleration to linear acceleration and relating it to force. And it will probably help you figure it out ,
