1. For a truss element, the length is 4, Section is A and the Young's modulus is E. The angle measured from the global to the local x-axis is 45°. Please write out the stiffness matrix [k] in global coordinate for this truss element. 2. How many DOFs does a simple beam element has? What are they? = 3. If we accept the cubic displacement field v(x) = c + Cox+ c3x2 + 4x3, please give out the shape functions and the
matrix.
