Because these systems may contain hundreds, if not thousands of equations, computers and software are used to solve them.ДЄfter this lesson, students should be able to: Engineers have to solve a wide variety of problems that requires finding the solution of one or many systems of linear equations. Engineers use sophisticated computer programs that solve all the equations resulting from a given problem solution. This engineering curriculum aligns to Next Generation Science Standards ( NGSS).Дetermining the strength of structures is extremely important in civil and mechanical engineering. The method of joints is the core of a graphic interface created by the author in Google Sheets that students can use to estimate the tensions-compressions on the truss elements under given loads, as well as the maximum load a wood truss structure may hold (depending on the specific wood the truss is made of) and the thickness of its elements. This method is known as the вЂњmethod of joints.вЂќ Finding the tensions and compressions using this method will be necessary to solve systems of linear equations where the size depends on the number of elements and nodes in the truss. In this lesson, students learn the basics of the analysis of forces engineers perform at the truss joints to calculate the strength of a truss bridge.
