| Summary: | The problems of measuring grain pressures in a grain bin are analysed. The difficulties in measurements
in the past are critically studied and an attempt is made to minimise them in the present set-up. The important
steps in instrumentation while fabricating and their effect on the results are indicated. The model bin with
strain-gages affixed is examined for the measurement of grain pressures. Its use as a proper and convenient
. measuring element is evaluated.
It is found that the electric resistance strain gages for measuring the horizontal and vertical strains in
the wall of a cylindrical bin are useful in observing pressure changes of the grain pressures on the wall. |
