Problem $3$

Draw the complete axial force, shear force, and bending moment diagrams for each member of the frame shown in Figure $3.$ The members are pin connected at A$,$ B$,$ and C$.$

In addition to solving the problem by hand, use MASTAN to check your results. You only need to print out screenshots of the MASTAN SFD and BMD to document your work, but you want to make sure you're getting the same results as your hand calculations. A key item I will be looking for is the moment at B you get from MASTAN. It must be zero because B is a hinge. To get the right answer you must insert a hinge at B in your MASTAN model. How do zyou do this?
