Procedure
1. Place the Utility Mount near the top edge of the Statics Board. Loop a thread approx-
imately 45 cm long through a Cord Clip and attach the Cord Clip to the mount.
2. Attach a 10 g mass to the thread and adjust the length of the thread so that the pendu-
lum is as long as possible on the board.
3. Measure and record L, the length of the pendulum from the pivot point to the center
of mass of the hanging mass. Record m, the hanging mass.
4. Set the mass swinging but keep the angle of the swing reasonably small (less than
20°). Measure the time for 30 oscillations. Record the total time.
5. Repeat the measurement five times.
6. Change the mass. Repeat the procedure for a 20 g hanging mass and then a 50 g hang-
ing mass.
7. Change the length. Repeat the procedure for the original mass and two different pen-
dulum lengths; one-half of the original length and then one-quarter of the original
length.
