Chapter 5, Problem 50P
| Three identical 6.40 kg masses are hung by three identical springs, as shown in Figure 5.60. Each spring has a force constant of 7.80 kN/m and was 12.0 cm long before any masses were attached to it. (a) Make a free-body diagram of each mass. (b) How long is each spring when hanging as shown? (Hint: First isolate only the bottom mass. Then treat the bottom two masses as a system. Finally, treat all three masses as a system.)
