10.4-9 The continuous frame ABC has a pin sup- port at A, roller supports at B and C, and a rigid cor- ner connection at B (see figure). Members AB and BC each have flexural rigidity EI. A moment Mo acts counterclockwise at A. Note: Disregard axial defor- mations in member AB and consider only the effects of bending.

Please help me!

I need just (a), thank you

10.4-9 The continuous frame ABC has a pin sup-
port at A, roller supports at B and C, and a rigid cor-
ner connection at B (see figure). Members AB and
BC each have flexural rigidity EI. A moment M, acts
counterclockwise at A. Note: Disregard axial defor-
mations in member AB and consider only the effects
of bending.
(a) Find all reactions of the frame.
(b) Find joint rotations 0 at A, B, and C.
(c) Find the required new length of member AB in
terms of L, so that 0, in part (b) is doubled in
size.
