Basic Idea:

• Determine the model equation that describes the relationship between period and length for a square pendulum.

	What:	How Many:	Where:
	Square Pendulums	All that we have (assorted sizes)	Majors storeroom, shelf A2
	Square Pendulum support bar	1	Majors storeroom, shelf A2
	Long metal rod (1 m x 0.02 m)	1	non-Majors storeroom, shelf B5
	Large bench clamp	1	non-Majors storeroom, shelf C4
	Right angle clamp	1	non-Majors storeroom, shelf B3
	Photogates	1	non-Majors storeroom, BB3
	Wood Metersticks	1	non-Majors Storeroom, shelf AA1
	Meterstick calipers	2	non-Majors storeroom, shelf AA3

Notes:

• Lab Setup (photo details):
  • Arrange gate on timer so that it points upwards, as shown at right
  • Sort pendula by size and place on small movable table. Place the unknown pendula on the instructor's bench. Make sure that the pins hang over the edge of the table.
  • Unknown pendula lengths:
    • A: 13.1 cm
    • B: 18.7 x 18.9 cm
    • C: 9.2 cm
    • D: 19.6 cm
    • F: 12.0 x 12.1 cm
    • G: 11.0 x 11.1 cm
