The continuous frame ABC has a pin support at A, roller supports at B and C, and a rigid corner connection at B. Members AB and BC each have constant flexural rigidity EI. A moment Mo acts counterclockwise at B. Note: disregard axial deformations in member AB and consider only the effects of bending. (Solve by the method of superposition.) RAY Ray Rcx Ⓡ (a) Find all reactions of the frame. (Assume that the +x-axis is to the right and the +y-axis is up along the page. Use the statics sign convention. Use the following as necessary: Mo and L.) RAx = = = L 8 = 8c = с B L/2 Mo (b) Find joint rotations at A, B, and C. (Enter the magnitudes. Use the following as necessary: Mo, L, E, and I.) 8A = (c) Find the required new length of member BC in terms of L, so that in part (b) is doubled in size. Lac =
