For the centrifuge rotor and test tube given in Example 7.2 on p. 560, assume that all the test tubes are locked into their horizontal position and that the rotor is uniformly accelerated from rest to 60,000 rpm in 9.5 min. Determine, as a function of time, the forces and moments on one of the test tubes during this spin-up phase of motion. Assume that each test tube and its contents can be modeled as a uniform circular cylinder with a mass of 10 g, and ignore gravity.
