A small cantilever vibrometer is available for measurement of vibration frequency, but the specification sheet is lost, so that the properties of the device are not known. The instrument is calibrated by placing it on a large compressor in the laboratory which is rotating at 300 ± 2.0 rpm. The measured length for resonance conditions is 5.6 cm ± 0.2 mm. Calculate the frequency that the instrument will indicate when L = 10 cm ± 0.5 mm. Also, calculate the uncertainty in the measurement in this length.
