You must be present, in class, to submit homework and other
assignments.
Computer Projects: The computer projects are to be produced according to the
College of Engineering and Technology format Attached. Students will work in
teams of at least 2 students per group from different disciplines when possible.
Each group will be assigned a specific span and a specific type of truss to
design. The solution must include

Each team will be provided a set of data for the above truss.
1. Sketch the truss and using the data provided, calculate the coordinates of
each node by evaluating first the constants a 0 ,. a 1 a2.
2. Show all dimensions, element numbers and node numbers on the sketch.
3. Analyze the truss by hand using the section method and determine the
force in each member of the truss. Indicate if the member is in tension or
compression. Show all sketches needed for each free body diagram.
4. Show on another sketch the forces in each truss member and place a sign
+ for tension and – for compression.
5. For the material that you are assigned, find either from the library or the
WEB the allowable stress for that material in tension. For compression
members use half the tension allowable stress.
6. Use STRAN or SAP or any other software to find the force in each
member. Attach a print out for the computer solution with the appropriate
sketches.
7. Generate a table showing each element, the two nodes that connect the
element, the force in the member from the hand calculation, the force in
the member from the computer solution, the percent error between the
hand solution and computer solution, the allowable stress for each
member, the minimum area needed to satisfy the allowable stress, the
size of cross section of the area, the actual area provided from the
provided area, and the corresponding stress for the area provided.
8. On a new sketch, place the magnitude of each force on each member.
9. The equation for the allowable stress/ load relationship is given as follows:
P P P P P
Y = a 0 + a 1 x + a 2 x^2
