Team Homework Assignment #5 Due Date: Thursday – February 23, 2017 1. For problem 2 in homework assignment #4, calculate the vertical displacement at the internal hinge. 2. For the frame problem (problem 3) in homework assignment 4, calculate the horizontal displacement at A and the rotation of joint C. Verify your hand-calculated solutions using a structural analysis computer program. Submit a printed copy of the output file (one per team). NOTE: Your virtual force calculations ignore axial deformation. To simulate zero axial deformation in your program, input a very large area (1000 x the moment of inertia) for the members. 3. For the given truss structure to the right, calculate the horizontal and vertical displacements at joint D. Verify your hand- calculated solution for problem 3 using a structural analysis computer program. Write your hand-calculated results next to the computer-generated results at each node or joint (one computer output per team). THEY SHOULD MATCH!

Team Homework Assignment #5
Due Date: Thursday – February 23, 2017
1. For problem 2 in homework assignment #4, calculate the vertical displacement at the internal hinge.
2. For the frame problem (problem 3) in homework assignment 4, calculate the horizontal
displacement at A and the rotation of joint C. Verify your hand-calculated solutions using a structural analysis computer program. Submit a printed copy of the output file (one per team). NOTE: Your virtual force calculations ignore axial deformation. To simulate zero axial deformation in your program, input a very large area (1000 x the moment of inertia) for the members.
3. For the given truss structure to the right, calculate the horizontal and vertical displacements at joint D. Verify your hand- calculated solution for problem 3 using a structural analysis computer program. Write your hand-calculated results next to the computer-generated results at each node or joint (one computer output per team). THEY SHOULD MATCH!
