(a) Relative amplitude versus distance from the fixed end (1st mode of vibration), 𝐿_𝑐=100mm, 𝑏₁/𝑇=0.1. (b) Magnified view of Figure 4(a) at the location. (c) Relative amplitude versus distance from the fixed end (2nd mode of vibration), 𝐿_𝑐=100mm, 𝑏₁/𝑇=0.1. (d) Relative amplitude versus distance from the fixed end (3rd mode of vibration), 𝐿_𝑐=100mm, 𝑏₁/𝑇=0.1.
