Problem 17.9

Standing-wave frequencies can be measured very accurately. Consequently, standing waves are often used in experiments to make accurate measurements of other quantities. One such experiment, shown in FIGURE 17.10, uses standing waves to measure the free-fall acceleration g. A heavy mass is suspended from a 1.65-m-long, 5.85 g steel wire; then an oscillating magnetic field (because steel is magnetic) is used to excite the m = 3 standing wave on the wire. Measuring the frequency for different masses yields the data given in the table. Analyze these data to determine the local value of g

CALULATING MOMENT OF INERTIA OF CIRCULAR DISK AND RING Shubham kc St. Cloud state university Introduction The main objective of this experiment was to find the relation of moment of inertia with angular velocity and torques. In this experiment, we took the disk and a ring of mass 4710±5 g and 4214±5 g respectively. We also measured the diameter of both disk and the ring. The inner diameter of the disk was 1.98±0.02 cm and for the ring is 22.5±0.02 cm and the outer diameter for the disk and ring was found to be 25±0.02 cm and 25.4±0.02 cm respectively. We also measured the diameter of the spinner which was found to be 4.89±0.02 cm. 1 2 Id= 2 MR (i) where, Id=moment of inertia of disk, M= Mass of the disk, R= Radius o
