1) If a chain of 35 identical short springs linked end-to-end has a stiffness of 400 N/m, what is the stiffness of one short spring?
2) 10 identical springs are placed side-by-side (in parallel), and connected to a large massive block. The stiffness of the 10-spring combination is 3100 N/m. What is the stiffness of one of the individual springs?
