A steel rod of length 1.44 m is clamped at a point 1/4 of its length from one end. The ends of the rod are free to vibrate. If the velocity of longitudianl wave in steel is 5000 m/s, find the frequency of the first three allowed harmonics. Make diagrams to show the three standing waves.

2. Relevant equations

f (frequency = n V/ 2 L

3. The attempt at a solution

All you have to do is plug in the variable. What I would like to know is how my freinds or classmates found the harmonics.

For frequency one they use 2 harmonics

and for F2 they use 6 harmonics

and for F3 they use 10 harmonics.

How did they figure that out.

n = harmonics
