A frame ABC is loaded at point C by a force P acting at an angle Î± to the horizontal (see figure). Both members of the frame have the same length and the same flexural rigidity.
Determine the angle a so that the deflection of point C is in the same direction as the load. (Disregard the effects of axial deformations and consider only the effects of bending due to the load P.)
