A thin rod of length ll swings at small amplitude with the pivot point at one end, with a thick rod of length LL and radius RR attached on the other end. The thin rod has a mass mm = 0.14 kg, and the thick rod a mass of MM = 1.36 kg. The radius of the thick rod is 0.09 m. If ll = 0.86 m and LL = 0.06 m, what is the period of oscillation? Answer in s.
