The first electric generators used direct current, so they needed to be reversed manually on a regular basis in order to work properly. Nikola Tesla saw this as an inefficient way to produce electricity. As a result, Tesla used the idea of the rotating magnetic field, which had been developed by François Arago, to invent the induction motor, which reverses automatically. How is this an example of a scientist applying creativity to solve a problem? Tesla investigated a new problem that no one had considered before. Tesla used another scientist’s research to help develop his own solution to a problem. Tesla designed a new experimental method for research. Tesla invented an entirely new concept to replace an inefficient design.

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?
