what are the major knowledge gaind by doing the simply suported beam experiment, deflection of beam testing ?

is the theoritical equation for the deflection valid in predicting beam deflection?

Solution

In order to verify the theoratical formula\'s, some one has to perform the real experiment and compare the diflection with the theoratical one.

While performing the simply supported beam testing (or any other beam), a personn can gain the knowledge of solid and structural mechanics, applications for using simply supported beam in differnet area, about electrical sensors, electric circuitary, reading measurements, jigs,rigs, fixtures etc.

Because, it is impossible to design and fabricate an universal rig which will be used to measure beam deflections as same as in theoretical one, there are some errors reflected in the experimental readings.
For simply supported beam with central point load this variation is around 0.8% .
Eg. For 9.81 N load Experimental deflection : 0.05 mm whereas theoretical deflection: .05041mm.
