Problem 3 (same as Problem 2): Use Abaqus software (thin beam elements) and evaluate 0 at B and reaction moment at A and compare those two with the solutions obtained in Problem 2. MUST show S11 stress contour. (30 points) Use E=107 lb/ft, I= 1/12 ft (use square cross section with a=1, b=1). Use 4 elements for beam AB and 2 elements for beam BC 200 lb/ft 30 ft- B. Name: Profile-1 Shape: Rectangular a: 1 b: 1 +10 ft 2400 lb
