Question

The graph below shows a measurements of the angular velocity from the rotary motion sensor along with a line fit, as taken by DataStudio. The hanger mass was 24.0 g and the pulley radius is 23.7 mm. An object different from either the ring or the disk was attached to the turntable. From the information in the graph and what is given above, calculate the moment of inertia of the rotating turntable plus the object attached to it. Assume g = 9.81 m/s2 and that friction can be ignored.

y intercept is -8.532

Explanation / Answer

w = alpha t .

alpha = slope = 24.305

mgr = I alpha

=> I = 2.29*10^-4
