Fig. 4.2.2 — Influence of ratio of mass of cushioning (m^) to mass of packaged article 

 (mh) on acceleration ratio. The numerator of the acceleration ratio is the maximum 

 acceleration (G„) in the n*'' mode of vibration transmitted through the cushioning. The 

 denominator of the acceleration ratio is the maximum acceleration (Go = y/lhki/rmg) that 

 the mass m^ would experience if the mass of the cushioning were negligible. See equations 

 (4.2.15), (4.2.14), (4.2.9). ^

Fig. 4.2.3 — Influence of ratio of mass of cushioning {vie) to mass of packaged article 

 on frequency ratio. The numerator of the frequency ratio is the frequency (w„) of the 

 n**" mode of vibration transmitted throug h the cushioning. The denominator of the 

 frequency ratio is the frequency (co„ = Vki/m^ of vibration of the mass rm neglecting 

 the effect of the mass of the cushioning. See equations (4.2.9), (4.2.13), and (4.2.3).
