B4-03: SPRINGS IN SERIES AND PARALLEL

PURPOSE: To show static series and parallel combinations of springs.

DESCRIPTION: Two springs of equal spring constant k are combined in series and in parallel. By measuring the extension of the spring combination one can determine the effective spring constants:

k(parallel) = k(1) + k(2)

1/k(series) = 1/k(1) + 1/k(2)

SUGGESTIONS:

REFERENCES: (PIRA 1R10.30.)

EQUIPMENT: Frame with two identical brass springs, two 200 g masses, spring coupling stick, and two-meter scale, as photographed.

SETUP TIME: 5 min.
