You are requested to solve the question on a piece of paper mentioning clearly all the formulas steps on it.Please solve correctly as it is the important task for our final exam and failure to do this will result in the failure of subject so be extra vigilent while doing this task.

Q2) Consider the beam in Figure 2 and answer all questions given below. E=210GPa and I= 3.05104m4 a) Explain with the help of calculations, how many rows and columns are required in the global stiffness matrix to represent the below system. [CLO1-PLO1-C2:2marks] b) Use the 2D direct stiffness method and create local as well as global stiffness matrix. [CLO2PLO2-C2:5marks] c) Examine the system below using the direct stiffness method to calculate the following unknowns i. Global deflection matrix [CLO4-PLO2-C4-3marks] ii. Global force matrix [CL.04-PLO2-C4-3marks] iii. Local deflection matrices [CLO4-PLO2-C4-3marks] Figure 2. Beam Element
