Moreover, the bending natural frequencies seem to be in a quite symmetric trend (increasing/decreasing in an opposing fashion with the inter-beam angle getting farther from 90°), while the out-of-plane natural frequency has an increasing trend over the whole range of the angle presented in Figure 7 .
