Question: The steel curved bar shown has a rectangular cross section with a radial height h = 6 mm, and a thickness b = 4 mm.

The steel curved bar shown has a rectangular cross section with a radial height h = 6 mm, and a thickness b = 4 mm. The radius of the centroidal axis is R = 40 mm. A force P = 10 N is applied as shown. Find the vertical deflection at B. Use Castigliano€™s method for a curved flexural member, and since R/h R B
