A two span continuous beam with loadings as shown in Figure, with supports A and C as fixed and support B as roller. Assume Young's modulus of material and moment of inertia of sections as constant throughout. The slope defection equations formulated for the span AB are : (Notations : M indicates moment and θ indicates the slope at the respective points)
