(a) Relative amplitude versus distance from the fixed end (1st mode of vibration)  𝐿₁=0.015m,  𝐿₂=0.85m,  𝑏₁/𝐷=0.1, and  𝑏₂/𝐷=0.1. (b) Relative amplitude versus distance from the fixed end (2nd mode of vibration) 𝐿₁=0.015m,  𝐿₂=0.85m,  𝑏₁/𝐷=0.1, and  𝑏₂/𝐻=0.1. (c) Relative amplitude versus distance from the fixed end (3rd mode of vibration)  𝐿₁=0.015m,  𝐿₂=0.85m,  𝑏₁/𝐷=0.1, and  𝑏₂/𝐷=0.1.
