Bridge Write Up The problem that we have is we need to find a bridge that will fill a gap that is 12" long‚ and 2.5" wide. Our objective is to build a bridge that can hold up to 2.5kg at the most. The bridge must have a length at least 3inches‚ and a width of 2.5inches. Some constraints that we have are no more than 10% of the bridge may consist of "bulky" members made from two pieces of balsa wood. We can only use 15 pieces of balsa wood‚ and if we use string it has to be attached in a simple

A Wheatstone bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuit‚ one leg of which includes the unknown component. Its operation is similar to the original potentiometer. It was invented by Samuel Hunter Christie in 1833 and improved and popularized by Sir Charles Wheatstone in 1843. One of the Wheatstone bridge’s initial uses was for the purpose of soils analysis and comparison.[1] -------------------------------------------------
