Which object do you expect to reach the bottom of the inclined plane first? Why? 2. Which object (hollow sphere, disk and ring in Experiment 8.2) has the largest moment of inertia? Does the object with the largest moment of inertia reach the bottom of the inclined plane first (in the race described in question 1)? ToldsT ni evian rhiw mab lla eshmmmue .2 3.

Figure 3 shows thin-walled cylinder and annular cylinder. 1 = MR (a) Calculate Iring (theory) using the measured data 2 1 = - M(R, + R2 ) R of ring radius in Table 1 to show that the two formulas I = MR' and I = - M(R, + R2) give R 2 2 RI essentially the same value of Iring (theory) for the Thin-walled ring used in Exp 8.2 (error is within 3%). hollow cylinder Annular cylinder Show that for a very thin-walled hollow cylinder
