You will analyze the normal and shear stresses in the neck of the classical guitar shown below. The model is a Yamaha CG-IIIC. Also, optimize the design to minimize the cross section; consider stress and deflection requirements The strings lie 1/8 in above the neck at section A-A and 1/4 in above the neck at section B-B. You can think of each cross section as a half ellipse (primary part of neck) and a rectangle (fingerboard) attached together using wood glue. Please begin with the following tasks: Draw the shear, moment, and tension-compression diagrams from section A-A to B-B. Use the total set tension (83.1 lb) given in the chart below. Assume: *The weight of the neck is irrelevant The co-efficient of friction between the plastic nut and strings are .04 Find the maximum normal and shear stresses and where they act (x, y, and z). Solve this for: Moment at the centroid A changing moment throughout the cross section (created from forces TI and T2). Example Tension Chart: Classical Guitar Strings (D'Addario Pro Arte Dynacore). This chart gives the tension in each string as well as the total tension. This is the same tension as given as T2 above.
