In this paper, we investigate measure synchronization (MS) in a nondissipative coupled-pendulum system suspended from a common beam. The system consists of several identical pendula hanging from a common beam that are indirectly coupled through the movements of the beam. We find that as the ratio R of the mass of the common beam to the mass of each pendulum decreases, which, in turn, increases the coupling strength between the pendula, the coupled-pendulum can achieve MS, including partial MS and complete MS, below certain threshold values of Rc. The energy characteristics of the MS are discussed. It is found that the pendula reach frequency locking at the MS transitions. Furthermore, by employing Poincaré section analysis, we reveal the dynamical mechanism of MS transitions.
