An indeterminate girder system is shown below with a uniform loading and a point loading. It is determined that the internal roller B settles down by 1.2 in. Assume that the modulus of the girder is $E=30000\mathrm{ksi}$ and the girder section's moment inertia $1=3000{\mathrm{in}}^4$ ). (1) Using the slope-deflection method, solve for the internal moments and the rotation at B. Need to use the fixed-end moment table handout for FEM's. (10 pts) (2) Draw the resulting shear and moment diagram for the beam (10 pts) [to get full credits, the shear or moment diagram must be placed in a coordinate system, and key values of shear/moment should be marked in the diagrams].
