EAS 209-Fall 2010 Instructors: Christine Human 11/1/2010 1 Lecture 30-Combined Loading Lecture 30 Combined Loading To date we have calculated the stresses due to: LOAD STRESS EQUATION CH FIGURE Centric axial load Normal APx1,2Torque Shear JTxy3 Bending Normal IMyx4 Transverse Load Shear ItVQxy5,6Internal Pressure Normal tpr2127 Many structures are subjected to a combination of loads. We can determine the state of stress at a point by finding the stresses due to each load, then apply the principle of superposition to obtain the total stresses. Today’s Homework: MVEAS 209-Fall 2010 Instructors: Christine Human 11/1/2010 2 Lecture 30-Combined Loading We will examine a slender structural member subjected to arbitrary loadings and find the maximum stresses at points H and K. The general approach is to pass a section through points of interest and determine the force-couple system at the centroid of section required to maintain equilibrium. In 3-D, system of internal forces consist of three force components and three couple vectors.Which forces cause normal stresses? Which cause shearing stresses?
