Experimental Procedures

1. Use a span of L = 36 to 37" for the wooden cantilever beam and a span of L = 48 to 50" for the aluminum simply-supported beam.
    
2. Be sure to write down all of the dimension measurements for each beam.  Measure the length of the cantilever beam from the bottom support plate.
    
3. Zero the dial indicators with the weight hanger on the beam.
    
4. Using the lathe-bed beam station, load the aluminum simply-supported beam in 5-pound increments up to 50 pounds.
    
   • Place dial gage “a” at approximately one-quarter of the beam’s length and dial gage “b” at approximately the midpoint.
   • Take deflection readings at locations “a” and “b” for each load increment.
      
   
    
5. Using the Tinius Olsen 12-kip UTM, load the wood cantilever beam in 0.5-pound increments up to 5 pounds.
    
   • Place dial gage “a” at approximately one-half of the beam’s length and dial gage “b” at approximately the tip of the beam.
   • Take deflection readings at locations "a" and "b" for each load increment.
