• Shear and Bending Stress • Composite Members • Combined Stresses Hope deferred makes the heart sick, but a desire fulfilled is a tree of life (Proverbs 13:12)
Hope deferred makes the heart sick, but a desire fulfilled is a tree of life (Proverbs 13:12) When a member, such as beam, bends, fibers along its longitudinal plane experiences flexural stress. �� = �� � M = bending moment, � = distance from fiber with respect to neutral axis, � = moment of inertia about the neutral axis, �� = bending stress Neutral Axis – It is the axis where the bending stress is zero. It is usually located at the centroid of a cross-section. From the formula, �� is maximum when � is also maximum. Hence, the maximum bending stress is found at the outermost fiber of the cross- section. neutral plane neutral axis
