Problem: Ten identical steel wires have equal lengths Land equal "spring constants" k. The wires are slightly twisted together, so that the resultant wire has length Land is 10 times as thick as each individual wire. What is the"spring constant" of the resulting wire?    a.0.1k   b.k   c. 10k   d. 100k
