0.25 Hz (shown in Figure 4.16). This is the frequency at which our beam will vibrate
when the 500-N force is applied at the indicated position.
In automotive applications, it is extremely important for engineers from different
groups to work in conjunction with each other to avoid conflicting natural frequencies
(a condenser radiator fan module vibrating at 75 Hz would not want to conflict
with a steering column vibrating at the same frequency). This condition would cause
customer dissatisfaction by amplifying the vibrations and increasing NVH. A beam
