Members AB and BC each have length L and flexural rigidity EI. A horizontal force P acts at midheight of member AB. (a) Find all reactions of the frame. (b) What is the largest bending moment M max in the frame? C B L — 2 P (Note: Disregard axial deformations in member AB and consider only the effects of bending.)
