Pendulum (Mass-On-Rod) 2
Pendulum (Mass-On-Rod) 2 : A pendulum (Figure 1, top) that rotates about some axis with the mass on the other end of a rigid rod, or with the mass at the end of a stiff cantilever spring (the pendulum of many modern force-balance accelerometers and broadband seismographs). Because the rod can also rotate away from the normal to the activeaxis, this design may be affected by translational accelerations along the axis of the rod while it is offset, although such offsets are minimized in force-feedback and stiff (e.g., MEMS) designs. Mass-on-rod pendulums also are directly affected by rotational accelerations about the pivot axis. See also Figs. 5.4 to 5.7 of Chapter 5 in this Manual
