The tire has a mass of 180 kg and a diameter of 1.35 m. Your hands are a full diameter away from the contact point (the point on the tire that remains in contact with the ground). Calculate the minimum force you need to apply to the tire to start it rotating about the contact point, assuming the tire is initially horizontal. Assume the mass of the tire is distributed uniformly throughout the tire. N Flipping a tire HOW TO: TIRE FLIP LIVE DAILY EXERCISES Flipping a tire can be a great strength workout, especially for your legs. For this problem, we'll make a simplifying assumption that the tire is a flat disk. That has no impact on the answer for (a), but does make it easier to work out the answer to (b). 7 K Open in R Part (b) Homework Unanswered Due Oct 31st, 12:15 PM At a later time you have rotated the tire through an angle of 30.0. At that time, what is the minimum force you need to apply to the tire to keep the tire in equilibrium at that angle?

Note that there is also a force of static friction, but we're not asking about that. N Type your numeric answer and submit K Open in Reading The tire has a mass of 180 kg and a diameter of 1.35 m.
