Discussion

The actual failure load was 3,721.5 lb. and our predicted failure load was 4,219 lb. Therefore, the objective was not accomplished.

The implications of the results are that the wrong calculation where made.

Attachments: Diagram, Questions

4-Square Riveted Design:

Questions:

1. What is your predicted allowable load for each of the following types of failure?

Shear Failure	4,800 lb
Bearing Failure	7,000 lb
Tear-out Failure	5,625 lb
Tension Failure	4,219 lb

2. What is your predicted mode of failure and predicted load?

The predicted mode of failure is tension stress in the plate, and the predicted load is 4,219 lb.

3. What was your actual mode of failure and actual load?

The actual mode of failure was shear stress in the plate, and the actual load was 3,721.5 lb.
