Physics Lab 2: Cantilever Beam

Title:  Bending of a cantilever beam

Aim:To investigate the bending of a cantilever beam and to determine the mathematical constants involved in the equation x = kln

Hypothesis and Theory:The depression of a cantilever beam is given by the equation image00.pngimage00.png

The depression of a cantilever beamimage05.pngimage05.png, is related to its length,image12.pngimage12.png, by the equation image00.pngimage00.png , where

image26.pngimage26.png. The length of the beam varies with the depression according to the mass that has been used. If we plot a graph with these variables we will get a curve, but it is not clear from this curve what the values of k and n work out to be.

Conclusion

 Evaluation:

Limitations of the experiment:

  • The time allocated for the experiment was not enough for repeating the experiment to get more readings.

Weaknesses of the experiment:

  • The rulers used were not calibrated properly.
  • The rulers were bent; hence it will affect the length of depression.

Possible sources of error:

The possible errors that were made were parallax errors when taking the readings.

Possible improvements to the experiment:

  • More time should be allocated for the experiment so that the experiment could be repeated to get more accurate results.
  • Proper Calibrated Meter Rulers should be used.
  • Meter Rulers which are straight and not bent should be used.

    It may be cause by air friction or the stiffness of the meter stick. When a meter stick is deflected, it has the tendency to return to its original stage and the amplitude of the oscillation decreases. Period of the oscillation is increasing gradually and cause uncertainty to the data.

    All the resistors we used had a �5% tolerance, which seems right because all the different combinations of resistors didn't have a percent error greater than1.5% or less than -1.351%. * There are virtually no anomalies in the series circuit graph, as you can see in the graph that all the pairs are nearly equal.

    Force- The force imparted on the pendulum will change the velocity and thus the period of the pendulum. In this experiment no force was imparted on the bob during the trials, the only force present was gravity which was constant throughout the experiment.

    The wooden ramp was slightly bent at the top due to the force leaning on the table. After the table (going downwards), the wood seemed relatively straight due to the wall supporting it. The top of the ramp did not have any support therefore making a slight bend in the wood above the table mark.
