Determination of Bending Moment in Beam

Apparatus:

model beam, weights, deflection gauge, hangers.

Objective:

The purpose of this experiment is to record the deflection in beam experimentally and then compare it with theoretical value.

Procedure:

• Take a beam model and place it on a table in such away that it should be horizontal and firm.

• Record the length and cross section.

• Set the deflection gauge at a point where the deflection is to be measured.

• Bring deflection gauges value to zero before the application of load on the bar.

• Now apply load with the help of weight hangers

• Record loaded weight its location from left side of the beam.

• Record deflection when first of all the smaller dial has rotated.

• Each division of main dial is 0.01mm

• Also record deflection at any other point record location of that point and value.
