Figure11-45 shows a rigid structure consisting of a circular hoop ofradius R and mass m, and a square made of four thin bars, each oflength R and mass m. The rigid structure rotates at a constantspeed about a vertical axis, with a period of rotation of 1.0 s. IfR = 1.5 m and m = 2.5 kg, calculate the angular momentum about thataxis.
