A three-quarter ring curved beam, loaded by horizontal and vertical forces at point B, has a rectangular cross-section of bx2b. The distance from the center of curvature to the centroidal axis R is equal to 4b. The beam has an elastic stiffness of E and is fixed at A.
a)Find the normal stresses in the theta direction at the inner and outer surfaces at theta=90o.
b)Determinethe horizontal deflection at tip B. (You can neglect the transverse shear effect.)
