Each face of the pendulum is provided with a pair of holes, symmetrically situated on either side of the centre of the face.
shaker excitation •Force levels The requirements of higher aircraft availability, lower maintenance costs, and a more comfortable passenger/crew environment demand low vibration in helicopters. Suggestions. The pendulum setups were filmed using an off-the-shelf camcorder, with a stopwatch in view to provide timing data. Given my previous knowledge, I know that a pendulum behaves in an oscillating manner, meaning that the acceleration is always proportional to the negative distance. Such double pendulum data can also be used to determine the pitch gyradius kp about the y axis, and the depth “a” of the center of mass below the line B-D62.
