2 The Grand Canal a Milestone in Engineering Page 17 Math Engineers had to plan for the removal of silt to create The Grand Canal. Can you solve these problems that the early engineers might have encountered? a c b 1. Look at the illustration above. Side a = 131 feet, the different in height between sections of the great canal. Side c = 786 feet, the hypotenuse of the right triangle. Using this formula (a 2 + c 2 = b 2 ) and a calculator, determine the distance the engineers had to excavate (side b) to make the ground even. (Hint: take the square root of a 2 + c 2 to find your answer. 2. If 100 workers can complete the task of leveling the land in 50 days, how long would it take for 200 workers to complete the task? 3. It takes one hour and fifteen minutes to fill the first lock and two hours forty-five minutes to fill the second lock. How long will it take to raise a boat to the top level of the lock to continue its journey on the river?

Then, form a plan that would help eliminate all those problems. Be creative in your plans your idea may be something the Chinese can actually use to return the Yellow River to its original unpolluted and overused condition! A Source of Power Page 34 Timeline Create a timeline that shows how engineers would construct a hydroelectric dam on the Yellow River. Begin with choosing the proper site for the dam and end with the generation of electricity for the residents of the area.
