The answer is given!
A rigid bar issupported by a pinned support at point B and by two deformable barsatpoints C and D asshown in the diagram below. Each deformable bar has aYoung’smodulus of E and alength L. The bar attached at D has a cross-sectional area of A,andthe bar attached atC has a cross-sectional area of 2A. What is the displacement ofpointD and what are the forces in barsC and D when the load P is applied?

Shouldn't there be at least two forces at the point B since B is a pinned support?
