4. Measure the period as in the previous parts. 5. Find the percent difference between the predicted and experimental values. Part5: Combination of Parallel and Series Springs (three springs) 1. We will now try the same experiment on a system of three springs, as shown below. The spring immediately above the mass is the short spring. Again we have the combined mass of the 100-g mass, the 50-g mass, plus the mass hanger. 2. Find the effective spring constant for the springs as shown. 3. Calculate the predicted value of the period of the system Part 5: Mass on Three Springs in Series and Parallel Spring Spring 2 Spring 3 m KI K2 K3 Keff T t (10 T (exp) % Diff 1 ID ID ID (pred) cycles)
