I have a quiz tommorrow and i am reviewing the harder problems and i cant get started on this one(adsbygoogle = window.adsbygoogle || []).push({});

A bicycle Wheel is resting against a small step whose height is h=0.120 m. The weight and radius of the whell are W=25.0N and r=0.340 m. A horizontal force F is applied to the axle of the whell. As the magnitude of F increases, there comes a time when the wheel just begins to rise up and loses contact with the ground. What is the magnitude of the force when this happenes?

I dont kinwo where to start i knwo the formulas

t=FL

and that the sum of the forces =0 but i dont know where to start

Please help me get started

thanks
