The plane frame shown below has a pin at A and fixed support at B $.$ Answer the ff :

a$)$ What is the degree of Kinematic Indeterminacy of the structure?

b$)$ If the Slope Deflection Method will be used, what will be the unknown displacements$/$rotations that must be solved? Label the variables for these displacements$/$rotations$.$

c$)$ What will be the joint equilibrium equation$($s$)$ needed to solve the problem? Set$-$up the eqns.

d$)$ Do you need a shear equation to solve the problem? If yes, set$-$up the equation.

No need to solve numerically.
