Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The stress a bridge must carry in the form of cars - trucks - people - trains - etc. This weight or load is constantly changing. Hopefully a bridge will carry MANY times it's own weight.
