1. The document analyzes the natural frequencies and mode shapes of a single rectangular cantilever plate through mathematical, finite element analysis (FEA), and experimental methods. 2. The natural frequencies were first calculated mathematically using Euler-Bernoulli beam theory. The plate was then modeled and analyzed in ANSYS to obtain natural frequencies and mode shapes via FEA. Experimental testing was also conducted to measure the natural frequencies. 3. The results obtained from the three methods showed good correlation with each other, though some methods produced results with up to 20% error compared to others. Analyzing the plate through different techniques helped validate the results and understand the dynamic characteristics of the structure.
