Unformatted text preview: 3. There is an extension and a bending problem here. (Bending in z only since the section is symmetric). Extension: GDE EA ¢ ¢ u = f x ( ) = Q d x3 L 4 ˆ ˜ BCs u ( ) = EA ¢ u L ( ) = ku L ( ) Bending GDE EI ¢ ¢ ¢ ¢ w = f z x ( ) + ¢ m y x ( ) = p stp xL 2 ˆ ˜ stp x3 L 4 ˆ ˜ + M ¢ d xL 4 ˆ ˜ BCs w ( ) = w L ( ) = EI ¢ ¢ w L ( ) = EI ¢ ¢ ¢ w ( ) = K ¢ w ( )...
