Question

4) Figure shows a rigid structure consisting of a circular hoop of radius R and mass m, and a square made of four thin bars, each of length R and mass m. The rigid structure rotates about a vertical axis. Calculate the structure rotational inertia about the axis of rotation. (Rod: $I_{CM} = \frac{1}{12}ML^2$ and Circular Hoop: $I_{CM} = \frac{1}{2}MR^2$) Rotation axis R 2R

Step 1

The rotational inertia of a circular hoop about its axis of rotation is given by the formula: I_hoop = m * R^2 where m is the mass of the hoop and R is the radius of the hoop. Show more…
