![]() In SOLIDWORKS, we can animate this to get a better picture of how the frequency causes the object to oscillate. The first mode shape demonstrates the fundamental frequency (the lowest frequency) where the object first exhibits this effect. The bottom will remain stationary with no loads applied. The geometry consists of a thin leg structure made with strong plastic material. To demonstrate, below is a simple motor mount with supports.

One important consideration when studying a design is how natural frequencies can cause structures to undergo resonance. ![]()
