1. For the given beam, please write the Element Stiffness Matrices, then assemble the Global Stiffness Equations. Assume no bending normal to the plane of the paper. E = 200,000 MPa and v=0.3. For ab: A = 6 x 10 mm I= 200 x 100 mm J= 300 x 10 mm a 8m na 8m b D t 2. Using the beam and information found in Problem 1, the beam is now supported and loaded as shown. Calculate the displacements at a and b and then calculate the reactions. For be: A = 4 x 10 mm 150 x 10 mm J = 100 x 10 mm* 9 + 5m X Pc = 5kN 45( 5m
