Engineers design for everyone and consider all design challenges opportunities to problem-solve. The roller coaster in this photo is the largest wooden coaster in East China. It stands 32 meters tall, 1,060 meters long, and is capable of speeds of up to 91 kilometers per hour. Is the need to build a roller coaster should be considered an engineering design problem?
