Question

5. (Point 30) Daring the experiment of moment of inentia a large disk is used Diameter which attached to the disk is measured as 37.58 mm using a Venier Caliper. The disk" mass is 3 b 2 or and Radius is 11.26m 785m 85m 3.0 (Nm) 0 027 0 022 0017 0.012 a(rad/s2) 3.5 0.007 1.5 2.5 (a) Find the torque around the disk when 90 g is used in this experiment. (b) Find the torque around the disk when 90 g is used in this experiment (c) Find the experimental moment of inertia from the graph τ vs a using 90 g and 150 g. (d) If we trust our experiment has no error, find the experimental mass of this disk. (e) Find the rotated angle of the disk from t-0.000 s to t = 5.000 s in the 90g case. a)
