ABSTRACT
Deflections of a beam are important to be able predict the amount of deflection for a given loading situation. This experiment addresses determining the yield point for a material to fail, so the stress in the material does not have to reach to that point. This is where understanding beam deflection becomes a useful tool. This experiment is using beam deflection theory to evaluate and compare observed deflection per load values to theoretical values. Beam deflection experiment done by four parts. Part 1 -Simple Supported Bean, part …show more content…
Safe load for quarter-span given by instructor is 40 lb
9. Calibrate the dial gauges.
10. Load the simple supported beam at the mid-span in 5 lb and record the deflection of the beam at the point of loading.
11. Add 5lb until the safe load limit is reached and record deflections of the beam for each 5 lb at point of the loading.
12. Repeat same procedure (1 through 11) for quarter-span.

(Figure-1)-Simple supported beam at mid-span and quarter-span

Results of this part are shown in table1 and table 3

Part -2 Cantilever Beam
1. Calibrate the micrometer.
2. Measure the dimensions and record them.
3. Calculate area moment of inertia (I) using the equation-4
4. Calculate maximum permissible loads for mid-span using equation-3,where maximum stress = 18,000 psi
5. Calculate maximum permissible loads for end of the beam using equation-3, where maximum stress =18,000 psi.
6. Check maximum load with instructor.
7. Safe load for mid-span given by instructor was 22 lb.
8. Safe load for end of the beam given by instructor was 10 lb.
9. Calibrate the dial gauges.
10. Load the cantilever beam at the mid-span in 2 lb and record the deflection of the beam at the point of the loading.
11. Add 2lb until the safe load limit is reached and record deflections of the beam for each 2 lb at the point of the loading.
12. Repeat same procedure (1 through 11) at free end of the beam. (Figure-2) cantilever beam at mid-span and free end
