Testing
Test 1: Functionality
Test 1 will determine the actual input and output forces of the tool. The calculated output force is 630 pounds, and the required input force is predicted to be 60 pounds. The results of this test will determine how the tool will work during normal use. The force required to align the set of test trusses 1 inch will first be tested, then the force required at the handle to move the same set of trusses will be tested.
Experimental Data
Summary
Test 2: Maximum Stress
Test 2 will test the maximum stress in the tool during normal usage, which will occur in the connecting bar. The predicted value is 53,880 psi, which is expected to occur in the middle of the part. This test will consist of the part being subjected to a 630 pound tensile force, and strain gauges will provide the necessary data.
Experimental Data
Summary
Test 3: Rough Usage
Test 3 will be testing the tool for rough usage. This will involve testing the weakest part of the tool for deflection in the event that it is stepped on while laying on an uneven surface. This test will determine the overall deflection of the part, as well as any permanent deformation that may occur. Using a 230 lb load, the maximum deflection of the connecting bar is predicted to be 0.0124 inches, and no permanent deformation is expected.
