Range of Experiments
To measure the vertical bending deflection of the bar and to compare with theoretical predictions.
To assess the effect of eccentricity of loading.
Description
Sometimes
in the design of a structure, a tension member has to be offset from
the line of action of the force. The member then has to carry combined
tension and bending loads, the latter increasing with the eccentricity
of the load. The eccentricity is exaggerated to make visual appreciation
of the phenomenon possible. When the load line is outside the middle
third of a square tie bar, as in this experiment, the bending moment
predominates and the bending deflection may be considerable.
The
apparatus enables both the load and eccentricity to be varied. A 9mm
square section by 800mm long specimen is provided, together with dial
gauge and load hanger. Different shaped specimens can be manufactured in
the college workshop as required.
This equipment is part of a
range designed to both demonstrate and experimentally confirm basic
engineering principles. Great care has been given to each item so as to
provide wide experimental scope without unduly complicating or
compromising the design. Each piece of apparatus is self-contained and
compact. Setting up time is minimal, and all measurements are made with
the simplest possible instrumentation, so that the student involvement
is purely with the engineering principles being taught. A complete
instruction manual is provided describing the apparatus, its
application, experimental procedure and typical test results.
