The structure in Figure P5.33 is made up of a cantilever beam AB (E1, I1, A1) and two identical rods BC and CD (E2, A2). Let A1 be large compared with A2 and L1be large compared with the beam depth.

a. Determine the component of the deflection of point C in the direction of load P.

---

b. If E1 = E2 = E, the beam and rods have solid circular cross sections with radii r1 and r2,respectively, and L1 = L2 = 25r1, determine the ratio of r1to r2such that the beam and rods contribute equally to qP.
