Coarse aggregate is placed in a rigid bucket and rodded with a tamping rod to Volume of bucket= ½ ft3 Weight of empty bucket 20.
3 lb Weight of bucket filled with dry rodded coarse aggregate 69.6 Ib determine its unit weight. The following data are obtained: a. Calculate the dry-rodded unit weight If the bulk dry specific gravity of the aggregate is 2.620, calculate the percent voids between aggregate particles.

Answer:
The natural angular frequency of the rod is 53.56 rad/sec
Explanation:
Since the beam is free at one end and fixed at the other hence the beam is a cantilevered beam as shown in the attached figure
We know that when a unit force is placed at the end of a cantilever the displacement of the free end is given by
Hence we can write
Comparing with the standard spring equation we find the cantilever analogous to spring with
Now the angular frequency of a spring is given by
where
'm' is the mass of the load
Thus applying values we get
