WebThe flywheel of an engine has moment of inertia 1.10 about its rotation axis. Part A What constant torque is required to bring it up to an angular speed of 400 ... A string is wrapped several times around the rim of a small hoop with radius 8.00 cm and mass m kg. The free end of the string is held in place and the hoop is released from rest ... Web7 nov. 2024 · The ending energy is the rotational KE of the hoop about the axis, or (.5) I ω 2. To calculate I, note that the CM is not the center of the hoop, since the axis is at the rim of the hoop, so you need to use the Parallel-Axis Theorem Ip = I cm + Md 2. For a hoop, this would be I = MR 2 + Md 2 = MR 2 + MR 2 = 2MR 2.
