Why do engineers study weather data before building a solar farm?1 / 6

Solar panels only make a useful amount of electricity where there is plenty of direct sunlight. Engineers check years of sunshine data to pick a site that stays sunny most of the year.

What is a design trade-off?1 / 9

Giving up some amount of one desirable quality to gain more of another — for example, accepting more weight to get more strength. Almost no design can maximize every quality at once.

A failure is information When something engineers built breaks, that's bad news and also the only way to learn certain things. So investigators dig in carefully rather than quietly rebuilding and moving on. The flaw that caused one failure
