Problem $6$ For the beam and loading shown, there is an internal hinge $($a mechanism that does not transfer moments, equivalent to a pin connection, but it does transfer axial force and shear force$)$ at B that connects the two multiforce members a$)$ Draw the FBD of the members AB$,$ BCD$,$ and hinge B$.$ b$)$ Find the reactions at A and C and the internal forces that the hinge B is transferring between the two members. c$)$ Draw the SFD and BMD using the graphical method $($relations among load, shear, and bending moment$).$ No need to report changes in shear force and bending moment. d$)$ What are the values of shear force and bending moment just before and after the hinge B$?$ e$)$ Identify the values and their locations of maximum shear force, and maximum and minimum bending moments.
