Mmmm donuts....Consider a gigantic homogeneous intergalactic plain donut wedged in the following position under the influence of Earth's gravity. Determine the contact forces between the donut and the frictionless surfaces. The outer diameter of the super donut is 24.0km while the inner diameter is a conservative 12.35km (it messed up when I tried to slide it off the tray...but it is pretty stale and therefore perfectly rigid). The mass of said donut is 4.97 imes 10^(^(^()))8 kg and for those of you who may be curious, the caloric intake is on the order of 1.73 imes 10^(^(^()))17Cal..^(1). You may assume that the mass centroid lies concentrically within the donut.
