Reset Help easier It is easier to stay on the log if it is to get it rolling. $\alpha = I \cdot \tau$ If someone exerts constant force $F$ on a log with their feet, larger radius $r$ of the log causes a $\tau = r/F$ torque, according to $I = \frac{1}{2} mR^2$ But the angular acceleration of the log depends on both torque and moment of inertia $I$: linearly $\tau = F/r$ A log with a larger radius will have a larger moment of inertia, and (if the log is solid) a larger mass, according to smaller Since the moment of inertia increases with diameter, as does the mass, while the more difficult torque increases the angular acceleration for a large log will be than $I = \frac{1}{2} mR$ $\alpha = I/\tau$ $\alpha = \tau/I$ for a small log. larger $\tau = F \cdot r$ quadratically
