Consider the beam in Figure.5, assume material Yuang’s modulus E Gpa = 210 and 4 2 A m = × 4.0 10 , the inertia I to be constant throughout the beam, A force of 200N and a moment 500N.m are applied to the beam at mid-length. The left end is fixed support and the right end is pin support.

(1) please discretize the beam into two elements with node 1-3;

(2）obtain the global stiffness matrix

(3)obtain the nodal displacement and unknown rotations at middle nodal.
