The frequency of magnetostriction oscillators is determined, Ask an Expert

Academics

The frequency of magnetostriction oscillators is determined by the 1ength of the nickel alloy rod, which generates an alternating voltage in the surrounding coils equal to the frequency of longitudinal vibration of the rod, as shown in Figure.

Determine the proper length of the rod clamped at the middle for a frequency of 20 kcps if the modulus of elasticity and density are given as

E=30×10⁶lb/in² and p=0.31 Ib/in.3, respectively.
