Q2:Figure2 shows an idealized truss which has pinned and roller supports at the both ends
respectively Answer the following questions
1) Based on the free body diagram of the entire truss solve equilibrium equations and
find the reactions at A and L. (10Marks)
2) Using section methods or any other methods find the axial forces on each and every
member. (15Marks)

Q3:Consider the below continues beam ABCD subjected to different loading conditions
idealized as shown in figure 3. Also, it is considered as the support condition A only fixed to
the rotation and others subjected to roller joints. As it is a statically indeterminate system with
6 redundant parameters carry out moment distribution method to solve the problem to find
shear force, bending moment and reactions. (25Marks)
1) Find the Fixed End moments of beam segments AB, BC, CD?
2) Calculate the Distribution factors of the beam segments in each joint?
3) What you meant by carry over factor and support your definition with the above
beam?
4) Tabulate the Moment distribution analysis
5) Find shear forces at joints
6) Draw Bending moment diagram and shear force diagram
7) Calculate the reaction force at the supports.
