6. For the beam and loading shown, calculate (a) the equation of the elastic curve for portion BC of the beam, (b) the deflection at midspan, (c) the slope at B. The beam is W200X46.1 with E-200GPa and load density of 5000N/m with L=6m P=WL 5 A 112-11 W C X

A lightly welded steel beam shown in Figure 5 is continuously supported along its length. A downward concentrated load of 4P acts at Point C, and two downward concentrated loads P act at Points A and E. The beam with full lateral restraint is bent about its major principal x-axis. Determine the followings: a. Section type based on section slenderness; b. Effective section modulus; c. The maximum design value of P.
