ABSTRACT:
In an apparatus comprising strain gauges mounted on a cantilever beam to measure elongation due to bending under load, the invention provides means in combination with said cantilever beam whereby a load can be applied to said beam so that the strain is directly proportional to the effective length of the beam and errors in measurement which have been incurred by other methods employed in applying the load to the beam are avoided.
