Consider the beam with a spring element as shown below. Given E= 70GPa, I = 40 x 10-6 m4, and k 5000 kN/m, determine: 1. The global stiffness matrix for the structure. 2. The rotations at nodes 2 and 3. 3. The reactions at nodes 1, 3, and 4. 4. The forces (shears and moments) in each beam element. 5. The force in the spring element. 17 E, I 3m 10KN E, I 3 3 m An ^ Consider the beam with a spring element as shown below. Given E= 70GPa, I = 40 x 10-6 m4, and k 5000 kN/m, determine: 1.
