Write a 12 pages paper on measuring forces in truss members using strain gages. High levels of accuracy were found for this experiment.
Engineers design and construct various structures including bridges, houses and trusses just to mention a few. Engineering structures, such as a bridge, are supposed to carry a given load (design load) without failure with some allowance for additional loads, such as from wind. This calls for engineering design, which involves the determination of the most applicable shape of the structure, the best material to use, and the consequent determination of dimensions for every structural member. The determination of best material and material dimensions are aimed to ensure that the structure under consideration does not fail upon load application through the intended use of the structure.
An engineering structure is a combination of members so arranged and joined that they facilitate the structure to perform its intended task. When loaded, different members experience different forces in terms of magnitude and direction whereby some members are under tension and others are under compression. It is important to determine the magnitude of the force on every structural member and the direction of the force, which aids in designing various structural members so that they can withstand forces in them. This determination is also important in coming up with and selecting the best structural design that promises the best economy in terms of the number of elements and dimensions of each element.

There are two methods of analyzing forces in structural members, which include the method of joints and the section method. Engineers use any of the two methods to analyze the desired engineering structure based on the load to be applied and the point of application of the load. Engineers can also determine the actual forces acting through structural members using strain gauges, which give the actual magnitude and direction of forces through&nbsp.structural members.
