The supporting structure of a movable crate has the dimensions as shown in the figure. The radius of the inner fiber of the curved part is 15" and the radius of the outer fiber of the curved part is 20". sing the curved beam theory, determine the following: the normal stresses at point P on section A-A. Are these stresses compressive or (a) tensile? (b) the normal stresses at the most outer point on section A-A. Are these stresses compressive or tensile? (c) the normal stresses at the centroid of section A-A. Are these stresses compressive or tensile? (The location of the neutral axis with respect to the center of curvature of a curved beam having a rectangular cross section is given as: ra=h/ [ In (r/ri)] -15" R 18 2000 lb 5 80" ттшт 60
