A ride at a carnival has four spokes of length l to which small pods are attached at the ends that can hold two people. Each spoke has a mass of mspoke and is attached to a central axis. Each pod has a mass of mpod and each rider has a mass of mrider. Initially the ride is spinning with a rotational rate of 1.4 radians per second.

(a)Write an expression for the moment of inertia of the ride in terms of mspoke, mpod,mrider and l.
