Answer to question 1

Answer to question 2

Transcribed image text: 4. For the plane frame shown in the figure, using symmetry, find the global stiffness equation and apply the boundary conditions to find the reduced equation 3000 lb/ft 30 ft 10 ft 45° E = 30 106 psi A = 5 in. I = 200 in. Hint: for a uniformly distributed load, we have: W 3 L = III WL WL 2 WL 12 ** . WL2 12 L
