Students explore the field of engineering by making a bridge using spaghetti as their primary building material. Then they test their bridges to see how much weight they can carry before breaking.</summary><engrConnection>
		
			
				Many people in different branches of engineering work to build bridges. Civil engineers are responsible for design and construction of such structures, however they also work with mechanical engineers and material engineers to design the most stable structures. These engineers must consider many variables when creating plans, such as the distance to be spanned, where the bridge is being built, the expected type of traffic it will have to withstand, materials available, budget, and what the bridge will look like.
